Knife Sharpening Angle Guide

ESEE 6 Knife Blade

When it comes time to sharpen your favorite knife, it’s important to carefully consider the edge angle. Knives that are thin at the edge tend to cut better but at the cost of durability. Fragile edges tend to roll, chip, and go dull with less use than a knife with a more robust edge thickness. A thick edge is more durable but loses out on slicing tasks. Pairing the right edge angle (also called edge bevel) to your knife is an important element of maximizing your knifes performance.

Before we dive in, consider the thickness of your knife blade. A very thick blade will exhibit great toughness, but no edge angle (regardless of how thin it gets) will ever make the knife a slicer. At the same time, a very thin blade stock will lack stability even with a very thick bevel at the edge. It’s all about how the knife will be used.

Less Than 20 Degrees Inclusive

20 Degrees Inclusive Edge Bevels Are 10 Degrees Per Side

At 10 degrees or less per side, the lowest bevel angles are typically found on purpose-built tools that cut only soft and consistent materials. Such steep angles are incredibly fragile, and use is limited largely to straight razors, scalpels, and utility blades.

30 Degrees Inclusive

30 Degrees Inclusive Edge Bevels Are 15 Degrees Per Side

At 15 degrees per side the edge bevel is still quite weak and susceptible to impact damage under any type of chopping. Japanese chef knives frequently utilize a 30-degree inclusive edge bevel while western chef knives more often lean toward a slightly less aggressive angle. Some people have luck with sharpening premium steels to 15 per side, but that will take trial, error, and a lot of patience to find which ones can stand up with use.

It’s rare for a fixed blade or camp-style knife to be this thin behind the edge, but it’s not uncommon to find EDC-type knives or traditionals with a slicey bevel profile.

40-60 Degrees Inclusive

40-60 Degrees Inclusive Edge Bevels Are 20-30 Degrees Per Side

Knives sharpened to 20-30 degrees per side tend to best represent balance. Chop wood at the campsite and then run home to slice up tomatoes for a BLT. Your knife can do it all! There’s no better choice for an EDC knife.

Aluminum Knife Handle Material

More Than 60 Degrees Inclusive

60 Degrees Inclusive Edge Bevels Are 30 Degrees Per Side

Are we talking about a knife or a pry bar? But really, at 30 degrees per side this is getting a little ridiculous. Only sharpen your knife to a 60 degrees inclusive bevel in situations that require the most extreme edge holding.

Natural Knife Handle Materials

Single Bevel

AKA Chisel Grind

Single bevel knives (also known as chisel edge) are only sharpened on one side. Although it’s quite uncommon to see a single bevel pocket knife, this sharpening style is popular among Asian chef knives. The edge bevel can be extremely thin (0 degrees on one side and 15 degrees on the other). Knives with a single bevel can make extremely thin cuts.
