Graver narrowing tips
A long, thin shank can be useful, but there are drawbacks as well.

The bright side is that there is less material to grind away when sharpening, and that the view is less obstructed when engraving.

The disadvantage of a narrow shank is the lack of rigidity. An experienced engraver comes to realize that the object being engraved needs to be held securely in a vise to get the best results. If there is any recoil movement, things get difficult. The metal will seem to cut harder and more broken points will occur. The same principle applies to your cutter. When a long, thin graver is used with a power assisted graver, it will flex or vibrate with the result of power loss and more broken points. A thicker, shanked graver can make noticeably cleaner cuts than the same point on a long, slender shank when used in a power graver. That said, the effect is less pronounced when cutting fine lines.

A means for having a balance of both rigidity and a small tip is a taper rectangle shaped shank (similar to a knife blade). The "Narrower" template works to grind such a shank accurately.

Note: the 3 degree or 2 degree taper is recommended over straight or 1 degree tapers. If new to engraving stick with the 3 degree to keep the rigidity in the shank while learning.
$23 each. Sold in packs of five.
