Longunner, it can be as easy or hard as you want. They are full tang blades so just need slab handles. I use a band saw to cut the slabs to the thickness I want, then trace out the profile of the tang on them and cut them to shape on a scroll saw a tad over sized. I mark the hole locations for the rivets and drill them a little under sized then use a flat bottom drill bit to do a slight countersink for the rivet heads, then use a rasp and file to cut a bevel on the blade end of the slabs. (cut a slit in a piece of tubing and tape it to the blade to protect yourself) Then rivet the slabs on the blade and use a rasp and file to remove any extra wood down to the tang. Then I use a round over bit on a router using a router table to round out the edges of the slabs, sand and then soak them in food grade mineral oil and let dry. Done. Traditionally they used birch but I have used black walnut, hickory, ash and cherry. The cherry and walnut are very nice but cherry burns really easy on the router and takes more sanding. If you don't have the power tools it can all be done with hand tools, would just take more time and skill.
