We just finished the latest version of the Bladetricks Diyuk design:
After the original (full length) version, the karambit, the Mini karambit, and the Mini Gladius versions we decided to make the Mini Diyuk dagger version:
A symmetrical (double edge) grind was too obvious for the eye, so we opted for a false upper edge (False dagger then...).
Some specs:
6150 spring steel
OAL: 180 mm
Black G10 scales
