Can a similar light edge be crafted with new smithing or new metals? Possibly looking for an impact weighted small edge.

>look katar
Impressed into the metal is the image of a raven hovering over an anvil and holding a hammer and tongs in its claws.
>app katar careful

A katar trains the small edged skill.

You are certain that it could do:
dismal puncture damage
fair slice damage
moderate impact damage

no cold damage
no electric damage

The katar is dismally designed for improving the force of your attacks.

You are certain that the katar is terribly balanced and is well suited to gaining extra attack power from your strength.

You are certain that the katar is appreciably susceptible to damage, and is in pristine condition.

The katar is made with metal.
You are certain that the katar weighs about 40 stones.
You are certain that the katar is worth exactly 541 Dokoras.

slice: 08- s.heavy
impact: 06- s.mod

force: 03- poorly
balance: 03- poorly

force: 04- inadequately
balance: 04- inadequately
suitedness: 10- v.well
