Mmmm..Muelas.... Never did like them after I found that they forged the Steel Blade into an alloy handle on some and the others (Wiv a few exceptions) were not full tang......
I would be very tempted to shorten up on the guard (Take out the Ricasso). (Carborundum saw). And get the handle a bit longer that way.
Do you need the guard?
I have made Handles out of Oak and Beech without any problems however have always had full tangs..
Strangely I made a half tang knife handle outa Pine (Unknown type), to save a folder that had disintegrated...
Had only about an inch of Tang embedded into the Handle and the four inch blade went right up to the handle..
Proved to be a useful knife fer some considerable time.....
? TIG Weld more tang on? Wiv the handle in some jewellers cool-mount or similar to stop re tempering????
Just a few suggestions.....
