There’s no jinxing mate
A decent draw knife is a blooming lethal thing,
Because the blades not removable or easy to mount in a vice etc, there’s a very specific way to sharpen them
You need to watch the you tube vid where one handle is held against your chest .
You’ll know what I mean when you watch it,
And do it slowly , with a finger dangling down as a stop against the blunt end of the knife
I’ll get the missus to take a couple pics later , but try and watch a few vids,,,most are of Americans and are very very good
