Thread: Shapton 16k, mixed grit??

OK, I just got off the phone with Harrelson. We had a very nice conversation. I certainly would like to spend a LOT more time speaking with him.

Here are the points salient to this thread.

1. He says that the Shapton company's grits are accurate to within 10% plus or minus the identified grit size. This actually is a very high tolerance level given the sizes involved, and in fact they only developed the technology to more accurately assess grit sizes about 8 years ago.

2. Harrelson is not aware of any Shapton hone being comprised of any mixed grits, and he has worked with the Shapton company for a couple of decades.

3. Because he only is responsible for Shapton in the US, he cannot speak to, nor speculate on, the claims made by any European vendor, including Dictum. Regardless, please take note of point #2.
