Viewing Knife Edges Under Magnification

I just use an 10X hand lens that I bought for geology field work. I use it in conjunction with marker during sharpening to see just how close to the edge I am getting, and to characterize any chipping or other damage.

As far as I have seen the hands down best hand lenses for the money (or for considerably more) is the Belomo triplet (http://www.belomo.us/). The rumor I've heard is that the factory used to make the optics for Soviet spy satellites. They also make a 20x, but the higher the power the lower your depth of field.

These guys have great service, (http://www.geo-tools.com/lens.htm) and the lanyard they sell with the loupe really makes the package, and its a family business with competitive prices. . . . . . . .. The loupe is olde world craftsmanship at Eastern European prices ( even with the Monopoly money USD) , the lanyard is good old USA made by the niece of the owner.

I have the very same setup from Belomo via Amateur Geologist. Highly recommended. :thumbup:

It just happens I was on the lookout for such a magnifier. Thanx for the referal.
