If you want the flattest, most straight lapping stone available, this is the BEST. Just like they say, this one is true. I have spent a lot of money to realize I need to spend a lot of money to have a good sharpening system. I have other (several) diamond plates (of supposed exceptional quality) I used for lapping stones I have bought over the past few years and one day realized I should look at the lapping plate for straightness, not just take their word! None, not one, was true. Light blew right though all over all the plates, then I got out the feeler gauge. Made me ill. I have been spending hours, no days sharpening off these plates and got mediocre results wondering if it was me. Not anymore! If you want sharp, my advice is spend the money on Shapton to begin with, rather than like me where I now have all these useless diamond plates. I guess I could try like Rob said and sell them on eBay!

The flattest I have ever used!

I was thrilled with the item, and even more so with the level of service!

The plate seems to do exactly as advertised, though my skill at lapping as part of sharpening (by hand, without jigs) is improving with practice, is not noticeably different. This is more a question of my ability and not the superior utility of the lapping plate. I am confident in Mr. Cosman’s assessment of the tools he recommends. And as always, the customer service and speed of getting merchandise in the Q are exemplary. Another “Job well done”.

very nice plate
