I mainly do full tang blades and I've done a couple of stick tangs, one leather before these.
Used a lot of thin cyanoacrylate to seal them and my word, a lot of sanding. Middle two in top pic spoken for, two to see what happens.
I'm quite pleased and just need to start the sheaths now, but work is calling tomorrow, it'll have to wait a few days....
