howdy all!! i am using an amk-75 1x30 belt sharpener to sharpen the knives i am making. i use 120-220-320-600-800-1000-5000 then power strop them to remove burr. they are sharp as far as shaving arm hair but they are not cutting phone book paper. I feel they could be sharper. any ideas? i read in a post that the AEB-L benefit from stones over 5k but i dont know how that works in belt world. As always thanks for reading or any thoughts on this.

Try to skip power strop and remove burr by hand ?
 
Might be a burr. I test with McMaster catalog pages, and if the knife hangs up, dragging the edge through the end of a 2x4 usually solves it. I sharpen by hand and usually stop at much lower grit, 1200 at the most.
 
its funny that you have both said to stop at a lower grit as the knifes generally feel more sharp at say 400 grit than 1000. I use to not power strop but run knife through soft wood to remove burr. I feel the knifes are sharper after power strop (just my opinion).

I sharpen kitchen knives on 100 grit ceramic , that edge bite like hot steel
Sharper but they are not cutting phone book paper ?

Have you tried the soft wood after power stropping? I sometimes use an MDF wheel with compound on cheap knives, and that can still leave a burr that makes the edge hang up cutting thin paper.
 
First, check the edge angle. If it is too round or blunt, lower the angle.
Next, make sure the burr is really gone. On knives sharpened repeatedly at multiple grit levels you can create a long burr. A stropping may not remove it fully. Slice the edge on the edge of a piece of pine 2X4a few times. That will pop off the burr. It will likely slice paper cleanly after that. I always do this before testing the edge.
 
Haha will try wood after stropping!
To be fair I never tried cutting phone book paper after low grit sharpening. Only after maybe 1000 or so I will try that as well! Thanks everyone
 
I prefer plain 20# copier paper and 60-75# card stock. It gives a more realistic gauge of cutting ability.
I usually slice up a 4X6 piece of card stock into 1/4" strips. It gives a good estimate of how sharp the blade is, how well it will cut, and removes any trace of a burr. After that I may take a few strokes through a sheet of copier paper to check that the edge is thin enough.
 
I stop at 400 and then power strop but I like a toothier edge. Has no problem with phonebook or magazine paper.

Like you said, test it at the lower grits and see how it performs!
