Knife Sharpening / Uneven bevel scratch Pattern
April 23, 2023, 04:47:00 PM
I am new to knife sharpening with the knife jig and it slipped when I got done to the heel of the blade on one side.  So I have a nice even bevel along the edge until I get to the heel.  At the heel, the scratch pattern is twice as wide.  I corrected the bevel, and tightened up the support, and the bevel looks great.  Except at the heal where I have the wider pattern.

I figured this can be sanded out but wanted to know if there are any tricks to use.  The wheel I started with was a 180 grit CBN.  I finished up with a 1000 CBN but still have these 180 scratches above the 1000 bevel. It's my own knife but it looks so bad.

I don't know, but for knife sharpening, I have three CBN wheels.  They are just a single layer of CBN material but for knives, I have not seen any wear.  180 grit is for re profiling.  Maybe not the correct word but when their are chips md other problems this squares it away.  A 600 grit is used for general knife sharpening and when I really want to get the perfect edge I go to the 1000 grit. 

As for wear I have not detected any.  Such a light touch is used.  Just make sure you take them out of the water once done and you dry them well.  I leave mine out on the bench overnight before I pack them back in the box.  For knives, this is all you need.  I go to diamond for carbide cutting tools and a better bonded CBN wheel when grinding tools steel and HSS.

I am new to the site but own 5 cbn wheels from Woodturners.  I have used them all in water with no problems.  Once I am done with a wheel I dry it off real good with paper towels.  I then leave them out in the open to air to dry before I put them back in the box they came in for storage.  Every once n a while I give the wheel a shot of WD 40.  Not on the cutting part of the blade but on the inner wheel and in the arbor.  WD stands for water displacement and is what the product was originally designed for.
