12 gauge shotgun shell crimp cutter by nailcannon

Last crawled date: 3 years ago

This is a simple hand tool to cut the crimp out of a shotgun shell. used for reloading cheap birdshot into cheap slugs.
There's a slot in the back for inserting the #1 exacto knife blade. It only goes in one way and the tolerances are tight enough that inserting it will require a bit of elbow grease.
version 1 has a smaller hole with almost not tolerance, but cuts closer to the edge, getting more of the crimp out.
version 2 has a larger hole and is much easier to use right off the bed. it tends to leave the lip on the crimp, similar to a roll crimp. Printing this one is preferred, but getting the slug in may be more difficult.
neither version currently has an easy way to replace the knife should it dull or break.
