Assemble and disassemble knives with free spinning pivots with confidence.
This 3d printed prototype bit holder fits between your fingers and allows you to hold the knife securely while loosening or tightening screws on a free spinning pivot.
A magnet at the bottom of the holder keeps your hex bits from falling out.
These prototypes are made from PLA, which is biodegradable, and are pretty tough. I have tested them with screws that were "locktited" together and they held up well. They are not indestructible and will break if crushed or bent harshly. Since these are 3d printed they can have artifacts or defects in the surface finish but these do not take away from the utility of the bit holder.
