a solution for stretched leather honing belts spring will help hold the

[napaknives]

You can use quarters to add length to the Viel.  Better yet, try putting an old cloth belt under the leather belt.  The leather belt will stretch to the length of the cloth belt, but it won't get "floppy" by over-stretching.  I use this trick on both the Viel and Kali machines.  This way I can leave the leather belt on a dedicated Viel while sharpening at farmers markets.  (I don't like to change belts while sharpening--it slows me down.)       ..........Dan
