This might be in the wrong section but I think I might get better answers here so... have a BM 552 with WilkinsGrips. I love it except for the finger choil. It puts "pointy" pressure on my middle finger when I use it. I would like to modify it and remove the choil. I believe I have read of others rounding out and modifying WilkinsGrips here on the forum. Anyone have any suggestions or a method for smoothing out the finger choil and rounding the edges a bit? Methods and supplies necessary would be greatly appreciated. Thanks!
