However, grinding to sharpness does not produce an edge that is ready to use. A ground edge has two flaws that must be removed by honing: 1. Coarse edge texture. 2. Burr. And there are additional reasons to hone. See the following section, The 4 Reasons for Honing. Why Sharpening

To get an exaggerated visual of this, think of a chip in a plane blade leaving an un-planed strip along your wood. A few dull micro-sections would make a blade feel draggy. In other words, edge inconsistency is not measured, even though it has a profound impact on tool performance.

Nov 08, 2020Some of the scalpel blades I purchased had to be ground on the top back edge to fit the No. 1 Xacto handle. Easily done with a grinding bit in a Dremel tool. I used the Xacto handle with the #11 scalpel blades for a number of years. No more broken tips on a scalpel blade and the blade stayed sharp for a longer period than the Xacto type #11 blade.

Aug 04, 2017The gradual rounding seems to be the effect when a blade is wearing normally rather than breaking under too heavy of pressure for the type of steel and bevel angle. Also worth noting, issues with short edge life can also be from burning the blade during grinding. Always start at the tip of the blade and work back.

Oct 13, 2010Straight razors are generally ground to end up with an edge angle of 12 to 18 degrees.. most somewhere in the middle, and this is of course useless for a knife, chisel or plane blade as the edge would just fold over or simply tear/crumble. Straight razors are unique beasts and can never be compared to the cutting edges of our more common tools.

Nov 21, 2012The shape of the blade, or profile, must be precisely ground. Grinding is the operation of using files or other abrasives to mechanically shape the steel into a functional blade. Grinding can be divided into two categories: grinding the blade profile and grinding the blade's edges (secondary and primary). Let's talk about the profile.
