Steve Earle is producing quality hand checkering tools and handles. They come nicely finished made of A2 steel and properly heat treated. I have no financial interest , just a satisfied customer that wants this supplier to be around when I need him. Steve also sells several rifle actions and supplies, in addition to custom making screws, springs and parts.

The handles are reasonably priced, but $22 each for a cutter head! WOW!!!

Ya but they come sharp and stay sharp longer. In my opinion they more than pay for them selves over the lower cost option and best of all they are available.

That type of tip can easily be re-sharpened by the user on an India stone, unlike the Dembart tips which are cut like a file and cannot be re-sharpened, so in the long run are fairly cheap.
