All, I'm struggling to learn to sharpen my chisels.

I purchased GREBSTK 4PCS Professional Wood Chisel Tool Sets Sturdy Chrome Vanadium Steel Chisel, 1/4 inch,1/2 inch,3/4 inch,1 inch which are supposed to have a Sharpening angle of 25 degrees.

I have tried everything from wet stones, to diamond plates and now trying the scary sharp float glass + sandpaper solution.

I have a sled that allows me to set the angle accurately. I set that to 25 degrees, but only the very back top the chisel blade is making contact.

I increased the angle to 30 deg and that helped a bit, but I'm nervous to get off the factory spec.

How do I get the front of the blade to contact? I know I could keep sharpening for a _long_ time and the chisel would eventually sharpen at that angle.

Thanks for any help.
