Once I had the basic wood shape, I began sanding.
I used a hand wood rasp for the rough start, then a random orbital sander.
You want it pretty thin when you are done, but not too thin. Thinner looks more elegant but it is up to you how brave you are.
Taper the edges so it is less boxy.
Here is the sword in the scabbard.
This also shows you that it is metal sliding out of a wood scabbard, so that Hollywood swa -swing noise is all fake.
It is a nice feel to it when it slides in.
I started at this end where I could see the shape, then worked down towards the tip.
This is as far as I took it. The next step is the leather work.
Go ahead, make a mess, make a wooden scabbard piece, have some fun.
