Repairing a Shun Premier chef knife and need to know if the damascus pattern will disappear if I thin the blade. I'm doing a tip repair I'm kind of stuck on what route to repair it.

It's not mine and I don't want to erase the pattern if there's nothing underneath the finish. I know that tip repair is done by grinding the top side of the blade but I have ground away much of the top portion and I don't want to alter the dimentions too much.

Given the drastic belly of the Shuns, I am considering removing some of the belly to meet the tip.
My concern is, by removing the cutting edge, the knife will need to be thinned a little. Since it is almost a zero grind to the edge the thinning process will creep into the damask pattern.

I have the equipment to polish afterwards but I'm not willing to take the chance of damaging it or giving someone something they don't like.

I have the ability to etch too if that would work.

I'll post some pics in a little while.

Here is the knife without the tip

Here is the final result. I decided to take just a little from the edge and reset a fresh bevel without thinning at all. I would say about 80% was removed from the spine portion.

Started with a coarse diamond plate working up to asagi finishing stone. Should just fall right through whatever's being cut. Passes paper towel test :ugeek:
The knife appears to have genuine damascus cladding that is surrounding the core. FWIW it should be possible to thin these shun and retain the pattern for aesthetics.

Feel free to move this topic to the sharpening section if its more appropriate.
