Max, this will be brief as I'm not a typist. Unscrew the pommel top. The handle and hilt assembly should then slide off. If a folding guard be careful of the leaf spring, you may have to depress to get grip off. The wire is held in place by wooden pegs, one at the bottem under the ferrule and one at top under the pommel. You can make them if they are missing. I'd insert wire in bottem hole, peg it and wind to the top and peg that. For the cypher there should be 3 holes in the grip. Fit the cypher pins thru the holes and bend them over with a small screwdriver on the inside of the grip so it will slide back on the blade tang. You may have to enlarge the holes slightly to fit them in. Reassemble. Be careful with the pommel top on removing, it may be rusted in place. Hope this helps. Barry.
