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.

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.

Comfy and Stay Put
Size: Medium, Color: (002) Black / Black / Halo Gray
These socks are honestly great. They’re super thin and light, so once you have them on, you kind of forget they’re even there. No bulky feeling in your shoes at all. The best part is they actually stay on. I hate no-show socks that slide down after five minutes, and these don’t do that. The little grip on the heel really works, so you’re not constantly adjusting them all day. They’re breathable too, which is nice if your feet run warm. They dry fast and don’t get that gross sweaty feeling. And there’s no annoying seam on the toe, so nothing rubs or feels uncomfortable. Basically, they’re just comfy, stay put, and don’t cause problems — which is all I want from socks.

Amazing but quality changed
Size: Large, Color: (002) Black / Black / Halo Gray
Love these socks so much, been buying them for about 4 years now!! Not giving them 5 stars anymore because the quality is different and not as good, durable and thick as before.
