I own Dave's of D-way and Ken Rizza's of WoodenWonder (I think). Both are very good guys and both of "theirs" sharpen my HSS beautifully. Dave's are heavier if that makes a difference to you and slightly more costly (but again...they are heavier). I also have the rounded edge versions and do not use it that often, but I do not regret buying it. Dway make an excellent CBN sharpening/honing stone. Now that I know how to use it (trial and lots of error), I love it. I also own Trends diamond card. It is less expensive, more portable because of its light weight, but I like Dway's better, Again, both will do the job...for me, it is a matter of what I practiced the most with.
