When you have a cladded knife and you thin behind the edge, what happens to the wavey pattern towards the edge? Does it become straight or???

the cladding gets thinner if you thin the knife? If you thin it long enough the "wavey patter" will disappear. The wavey pattern is there cause of 2 different metals and the reaction on them

The pattern will change. How it changes depends on how evenly the core steel and the cladding meet. Because of manufacturing tolerances, it's not likely that you'll have a straight line, but it could happen. You can also get "breakthroughs" where the core steel shows through the cladding. What will likely happen though is that the amount of core steel showing will increase and the "wavy pattern" you mention will change. For an example, look at the pictures of the thinned and etched Hiromoto Dave has posted in his sub-forum: http://www.kitchenknifeforums.com/showthread.php?3941-SALE-Hiro-AS-240mm-Gyuto-2nd

If you thin behind the edge, obviously the first thing being thinned, is the cladding. If you are concentraing your thinning near the edge, likely the transition/wavy line will move towards the spine some. The amount it moves is related directly to how much of the cladding gets removed. If the thinning is even, it will look nice and even, if an area gets thinned more by accident/over grinding, the result will be more core exposed in that area, and look uneven. It will not likely straighten out. the wavy pattern is there because of how it was forged, from hammer blows, or from the press used.

+1 on "breakthroughs." I've thinned a couple of Takedas that ended up, from bevel to spine, like this: core steel, wavy grayish cladding, a thin line of core steel (breakthrough), black cladding.
