If you want to keep the extremely perfect CRK grind, the tanto is a challenge on the sharpmaker. I have a CRK tanto, and a sharpmaker, but lack the patience to keep the two grinds perfectly separate. I end up sharpening the long edge'on the sharpmaker (carefully and only using the flats), and doing the tip on a strop.
I think to really enjoy the CRK tanto blade you need to be one of three kinds of people:
1- a person who is a collector and will not use the knife
2 - a free thinker who is totally OK with the tip morphing into some sort of spanto-ish shape after lots of hard use and random sharpening efforts.
3 - a reasonably skilled knife sharpener with patience.
I fit none of these categories, so I'm still a little unsure of the tanto. I like it mostly because I think it has something to teach me, if that makes sense.
