I am a custom slip joint knife maker. I have over 20yrs in the machinist/ toolmaker trade. I learned to make and grind knives from my father and a close friend of his that have been making fixed blade knives for about 12yrs. I use D2 and CPM 154 steel for my blades. The liners are mill relieved and the bolsters are integral. The blades are hand finished. If you have any questions, please call me at 618-823-7327.
