I have been fighting the idea of a guide. I found that the guide arm on my Tormek tended to move/bend enough to throw the whole thing off. The old Veritas guide I have has no way to register the side of a chisel or plane blade against something to make sure it is straight. I have been trying to do it all by hand, but I think a guide might help.
The Veritas MKII Honing Guide is obviously much easier to set a chisel or plane blade up in and the camber roller looks like it might enable me to get the consistent cambers I want. Is this the best answer for consistent results? I did some searching and found a positive comment about cambering with it from Derek Cohen which is about all the encouragement I need, but the post was on the MKII. Is there something better? Ok other than raw skill and persistence. I should add I have very good stones from Tools From Japan- 120, 700, 3000, 6000, 10000.
