How To Cut Antlers Off A Deer: A Step-by-Step Guide To Skull Capping And Pedicle Cutting

To cut antlers off a deer for a skull plate mount, make a precise, angled saw cut starting behind the eye sockets and extending downward to the back of the skull, completely bypassing the brain cavity. This process, known as skull capping, requires a fine-toothed bone saw and strict adherence to Chronic Wasting Disease (CWD) transport regulations, which mandate the complete removal of all neural and soft tissue. For crafting or shed replication, individual antlers can be sliced flush at the pedicle base using a high-TPI saw to prevent splintering the porous bone core.

Whether you are harvesting a trophy in the backcountry and need to pack out light, preparing a DIY skull plate mount, or salvaging antlers for knife handles and tools, knowing how to clean-cut deer bone is an essential skill. Improper cutting techniques can shatter the skull plate, damage the antler bases, or result in severe fines if you cross state lines with contaminated brain matter.

Anatomical Prep and Tool Kits for Antler Removal

Before making your first cut, you must understand the anatomy of a deer’s skull. The antlers grow from the pedicles, which are permanent bony projections of the frontal bone. If you want to keep the antlers paired and structurally sound for a wall mount, you must preserve the frontal bone connection by performing a skull cap cut. If you only want the antler material for crafts, you can cut them off flush at the pedicles.

To perform these cuts safely and cleanly, you must use the right tools. Wood saws have teeth that are too coarse, which will splinter the bone and ruin the integrity of the skull plate.

Mandatory Equipment Checklist

• Bone Saw or Hacksaw: A dedicated hand bone saw or a standard hacksaw fitted with a medium-to-fine bi-metal blade (18 to 24 teeth per inch, or TPI).
• Reciprocating Saw (Optional): If processing multiple heads, a reciprocating saw equipped with an 8-inch metal-cutting blade (14 to 18 TPI) provides clean, rapid cuts.
• Skinning Knife and Scalpel: A razor-sharp hunting knife to cap the cape and peel back the skin.
• Personal Protective Equipment (PPE): Safety glasses and a tight-fitting N95 dust mask. Inhaling aerosolized bone dust is highly hazardous, and aerosolized brain tissue carries biological risks.
• Scraper and Wire Brush: For removing the brain matter and muscle tissue from the underside of the cut bone.
• Sanitization Agents: Washing soda (sodium carbonate), Dawn dish soap, and 3% to 12% hydrogen peroxide. (Do not use chlorine bleach, as it permanently weakens the bone's collagen structure).

Regulatory & Safety Standards

• CWD Transport Laws: Most state wildlife agencies prohibit the transport of intact deer heads across state or county lines to prevent the spread of Chronic Wasting Disease (CWD). The skull plate must be completely free of all skin, muscle, cartilage, and brain tissue before transport.
• Dust Mitigation: Bone sawing produces fine calcium phosphate dust. Always saw in a well-ventilated area, preferably outdoors, and wear your respirator.

Step-by-Step Skull Capping and Antler Removal Process

This standard surgical method preserves the natural spacing, angle, and orientation of the antlers on a single piece of bone, known as the skull plate or skull cap.

Step 1: Skinning and Exposing the Skull Plate

You must clear away the thick hide, hair, and muscle covering the top of the skull to see your cut lines clearly.

1. Lay the deer head flat on a stable work surface, muzzle facing down.
2. Make a straight cut down the center of the skull, starting from the midpoint between the antlers, running forward to the bridge of the nose, and running backward to the base of the skull (the occipital protuberance).
3. Make "Y" shaped relief cuts from the center line outward to the base of each antler pedicle.
4. Using your skinning knife, peel the hide away from the bone. Work around the bases of the antlers, using the tip of your knife to slice through the tough connective tissue surrounding the burrs.
5. Pull the skin down past the eye sockets and down the back of the neck to fully expose the bare white bone of the frontal and parietal plates.

Step 2: Mapping the Cut Lines

Precision during this step prevents cutting too high (which splits the skull cap) or cutting too low (which cuts into the brain cavity, exposing you to prions and brain matter).

1. Identify the anatomical landmarks: the rear of the eye sockets (orbital arches) on the front of the skull, and the occipital condyles (where the skull connects to the spine) at the back.
2. Draw your guide cut line using a dark permanent marker.
3. Begin the line directly behind the eye sockets on the bridge of the nose.
4. Angle the line downward at roughly 45 degrees, passing directly beneath the pedicles of both antlers, and exit the back of the skull just above the spinal opening (foramen magnum).
5. Ensure the path is symmetrical on both sides so your mount will sit flat against a plaque later.

Warning: Do not attempt to cut through the skull while the skin is still attached. Hair and soft tissue will bind the saw blade, causing it to slip and potentially ruin the antler burr or cause severe physical injury.

Step 3: Executing the Primary Skull Cap Cut

The bone of a deer skull is composed of a hard outer cortex and a soft, spongy inner marrow. Consistent, steady pressure is required to cut through both layers without fracturing the bone.

1. Secure the deer head. If you are in the field, step on the snout or lower jaw to pin it to the ground. If you are in a workshop, clamp the lower jaw firmly in a bench vise.
2. Place the blade of your bone saw on your marked line at the front of the skull, just behind the eye sockets.
3. Draw the saw backward several times to create a guide groove in the bone.
4. Saw with smooth, long strokes. Apply light downward pressure on the forward stroke and release pressure on the return stroke.
5. As you approach the center of the skull, you will feel the resistance drop slightly as the saw enters the brain cavity, followed by increased resistance as it hits the back of the skull.
6. Support the antlers with your non-dominant hand during the final few strokes to prevent the bone from snapping and splintering under its own weight as the cut finishes.

Pro-Tip: If using a reciprocating saw, run the tool at a medium speed setting. High-speed cuts can friction-burn the bone, leaving a permanent black soot mark and a foul smell that is difficult to deodorize.

Step 4: Scraping and Cleaning the Skull Cap

To comply with transport regulations and prevent rot, you must remove all organic matter from the harvested skull plate.

1. Use a flat-edged scraper or a dull knife to scrape away the remaining skin and meat from the top of the skull plate.
2. Turn the skull plate over. You will see a portion of the brain cavity. Spoon out any remaining brain matter immediately.
3. Use a stiff wire brush and warm, soapy water to scrub away the meninges (the thin, tough membrane lining the inside of the bone).
4. Rinse the bone thoroughly under running water.

Step 5: Curing and Deodorizing

Residual oils in the bone will eventually turn yellow and emit an odor if they are not neutralized.

1. Submerge the cut skull plate (keeping the antlers themselves dry and out of the water) in a pot of simmering water mixed with two tablespoons of washing soda (sodium carbonate). Let it simmer for 20 to 30 minutes to degrease the bone.
2. Let the bone cool, then pack the underside of the wet skull plate with Borax. The Borax will draw out remaining moisture and cure any microscopic tissue particles left behind.
3. Allow the skull plate to dry in a warm, low-humidity area for 48 hours.

Comparing Antler Removal Methods and Tool Configurations

The optimal method for removing antlers depends on your final plans for the mount or craft project. Below is a comparative breakdown of the industry-standard cutting methods.

Common Field Failures and Antler Salvage Techniques

Even experienced hunters can run into trouble when cutting bone. Below are the most common failures encountered during antler removal and how to resolve them.

The Cut Ran Too Shallow (Splitting the Skull Cap)

• Root Cause: Saws naturally follow the path of least resistance. If you do not hold the blade at a steady 45-degree angle, the blade can drift upward, slicing directly into the base of the pedicle and splitting the skull plate in half.
• Actionable Fix: Do not panic or throw away the split pieces. Once the skull plates are dried and cleaned, drill two small pilot holes horizontally through the thickest part of the remaining frontal bone on both pieces. Thread a heavy-gauge steel wire through the holes, pull the two halves tightly together to restore their natural spacing, and twist the wire shut. Reinforce the joint on the underside of the plate using a thick layer of two-part epoxy putty.

Bone Splintering at the Exit Point

• Root Cause: This occurs when you reach the end of the cut and fail to support the weight of the antlers, causing the remaining thin shelf of bone to snap rather than cut cleanly.
• Actionable Fix: Use a file or an angle grinder fitted with a 120-grit flap disc to smooth down the jagged edges of the splintered bone. If the structural integrity of the plate is compromised, back the damaged area with fiberglass mesh and epoxy resin to prevent the cracks from spreading up into the pedicles.

Persistent Odor and Yellow Greening

• Root Cause: Lipids and oils trapped deep within the porous bone marrow are rotting because they were not properly degreased.
• Actionable Fix: Submerge the bone portion of the skull cap in a bath of warm water mixed with a high-concentration grease-cutting dish soap (like Dawn) for 24 hours. Rinse, dry, and then coat the bone in a paste made from 12% hydrogen peroxide and basic white whitening powder (available at beauty supply stores). Wrap the paste-covered bone in plastic wrap for 24 hours (keep the paste off the dark antlers to prevent bleaching them). Rinse with cold water and dry.

Frequently Asked Questions

How do you sanitize a deer skull plate for legal CWD transport?

To legally transport a skull plate across state lines, you must remove all soft tissue and brain matter. Scrape the bone clean, simmer it in water with washing soda to dissolve residual fats, and wash the plate in a 10% chlorine bleach solution or soak it in hydrogen peroxide to destroy any biological pathogens. Check your destination state's specific wildlife transport rules, as some states require official inspection.

Can you use a chainsaw to cut antlers off a deer?

No, using a chainsaw is highly dangerous and ruins the mount. The wide teeth of a chainsaw chain will shatter the bone, rip through the antler burrs, and spray brain tissue, grease, and bone fragments over a wide area, creating a severe biological hazard. Always use a manual bone saw, hacksaw, or reciprocating saw.

What is the difference between cutting at the pedicle versus skull capping?

Cutting at the pedicle slices each antler completely off its bony base, leaving you with two separate antlers and no connecting bone. This is ideal for crafts and handle carving. Skull capping leaves a portion of the skull intact to connect the two antlers, preserving their natural spread and angle for mounting on a wall plaque.

How do you prevent cut antlers from cracking or drying out over time?

To keep cut antlers from drying out and cracking, store them away from direct sunlight and extreme temperature changes. To protect the bone, you can apply a light coat of liquid wood stain to restore faded color, followed by a thin coat of matte polyurethane sealant or a rubdown with paste wax to lock in moisture.
