Steve is the best I recommend checking this out if you can!! Steve Smith--IFYCA I will be doing an Infinity Knife Seminar in Walla Walla Sunday January 22. If you are interested in joining post here on the wall as a comment or direct message me. Encouraging everyone to bring their Infinity Knife trainer or order one from Chris Woiler prior to the Seminar please order early allow at least 2 weeks to get the trainer as each are individually made. You can use our rubber trainers as well but it will detract some from your understanding.
