hapstone m3 or madedge?

Does anyone have any tips on how to get the Venev double sided stones to stay in the holder better. I've noticed some slippage. I think I'm going to try a piece of rubber grip mat for the ends, but if anyone else has any other suggestions?

So I finally setup my M3. Very easy to get started- I think it is pretty intuitive to use. I only used it on one paring knife with the Venev double sided stones- great results. Looking forward to trying this on some pocket knives soon. I don't think I would use this for every sharpening task, but certainly for any profiling, or on damaged edges. Highly recommend this for anyone considering a guided system.
