Making a snowman & half-snowman

[Shrub]

I dont like the handles for needle files.

Anyway, you may have to soften the blade (anneal) if fileing or else a needle file will loose its teeth

A needle file wrapped in smooth emry paper will be better or even better use an oil stone.

You wouldnt have to soften it then

I have been annealing the blade to file it, and then tempering it after.

how would emery paper or a oil-stone help?

maybe I've missed something blatently obvious

The finer the cutter the harder material it will cut.
