Description

Determining the sharpness of a blade requires precision and consistency beyond the standard methods like cutting printer or newspaper or shaving arm hair. To truly prove sharpness, professionals and enthusiasts rely on the BESS certified PT50 Series Sharpness Tester from Edge-On-Up.

The BESS (Brubacher Edge Sharpness Scale) standard, developed by Mike Brubacher, provides an accurate measurement of knife sharpness. Adopted widely, this user-friendly test method is trusted to determine the sharpness of blades.

Details

The PT50 Series of Edge-On-Up Sharpness Testers allows you to measure and quantify the sharpness of any tested edge. These systems measure the force in grams required to cut through a standardized and calibrated test medium. The displayed result is a number that indicates the relative sharpness of edges.

To provide more context, a table has been created to show how the score relates to the total BESS scale, ranging from 2000 BESS for an unsharpened knife to 0 BESS for the highest sharpness achievable. Knives with a score below 50 BESS are considered razor sharp. Lower BESS values indicate sharper blades, as less weight is required for cutting.

Fit and comfort
Size: 12, Color: Ch British Tan/Ivory
These have to rate as equal to any shoes I've ever owned. I know everyone's foot is shaped differently but when I slipped my feet into these I was immediately sure I had made the correct choice. Sizing is true. You note, I'm sure, that these are slip-on shoes. My experience with slip-ons has been mixed as sometimes the heel tends to slip due to the maker leaving room for the slip-on function to take place. When I got these I discovered that the opening for my feet was so tight I needed to shoe-horn them in and it wasn't particularly easy. The heel counter was "high and tight" but once I got my feet in the shoes it was heaven. Then, after a couple of days wearing them I can now slip my feet into these slip-ons with ease and the shoes grip my feet like a lace-up shoe can do. I have one other pair of Cole Haans in the same size 12. They are also a wonderful fit for me. I highly recommend.

Great shoes true to size

Great shoes, came with box. Brand new, true to size 11 US ! :) in my country they cost 270 USD so, really nice and very comfortable shoe considering i have plantar fasciitis. 3 month update: They get wrinkles pretty fast in just a few weeks due to the material, it’s not noticeable to others at all, but it’s worth keeping this in mind when buying this particular model.
