If you can set the Spyderco sharpeners side-by-side (as in a picture above), they might work.
I am aware of the angle difference. one of the deciding factors for buying the sharpmaker as apposed to a flat stone was the versatility... at the time i was sharpening knives, hoof trimmers, hatchets, even a machete and shop tools... its proven to be worth the investment.. im really hoping to find someone who has used it with their straight blade, if not, i'll just have to try it myself. i'm pretty confident it will do a good job, but it would also be nice to have someone's experienced opinion as well... if not, i'll just have to be the first to do a review on it!
