To cut carbon arrows cleanly, use a high-speed arrow saw with a sharp, fine-tooth carbide or diamond blade (like the modsaw). Rotate the arrow slowly while applying light, steady pressure into the blade rather than forcing the cut. Supporting the shaft close to the blade will dramatically reduce splintering. After cutting, lightly square the end of the shaft to ensure proper component alignment.

Carbon arrows cut best with diamond-coated blades, like the modsaw uses, designed specifically for composite materials. These blades stay sharper longer and reduce fraying. Aluminum arrows can be cut with fine-tooth metal-cutting blades, but many archers use the same blade for both materials to maintain consistency.

Building your own arrows can save $3–$8 per arrow, depending on components and brand choices. Over a dozen arrows, that often translates to $40–$100 in savings. Beyond cost, DIY arrow building allows for tighter tolerances, easier repairs, and the ability to tune and customize arrows exactly to your setup—benefits many serious archers value more than the savings alone.

At minimum, wear eye protection to guard against carbon dust and debris. A dust mask or respirator is strongly recommended when cutting carbon arrows, as fine carbon particles can be harmful if inhaled. In addition, we recommend using a vacuum to keep carbon dust away. Keeping hands clear of the blade, securing loose clothing, and using proper arrow supports further reduces risk.

Avoid cutting arrows to inconsistent lengths, using a dull or incorrect blade, or rushing the cut. Always rotate the shaft during cutting and apply light pressure to prevent splintering. After cutting, square the shaft ends so inserts seat flush—unsquared ends can cause wobble and hurt accuracy. Finally, don’t skip spin-testing after assembly to catch alignment issues early.

Ceramic bearings have a longer spin time, are more resistant to weather and humidity, and are self-lubricating.

Our diamond coated blades last the typical DIY archer a lifetime.

The nock-in measures the distance from the throat of nock to the tip of carbon.

Yes! The modsaw is capable of handling aluminum, carbon, FMJs, and wood arrows.
