How much steel to remove to cure chipping caused by overheating of steel?

[Nealoc187 10]

I had my skates re-profiled yesterday because I wanted to drop down to a smaller radius. I skated on them tonight and afterwards noticed a pretty significant amount of chipping at the very very toe of the blade about 1/4" of chipping on one, 1/2" on the other, on both the inside and outside edges. There is a little discoloration visible in the same area - the blades were overheated when they were profiled obviously. How much steel would I need to have removed to get out of the overheated zone? These are virtually brand new blades - they've only been sharpened probably 4-5 times including the two times they were profiled - so I'd really like to avoid springing for new steel. They are the old TUUK Plus steel (brand new never worn set of Micron Mega Air 90s I picked up on ebay).

Tough to tell, detailed pictures would help.

yeah - I tried to take some but the glare and that typical situation where the picture doesn't come out looking like it looks in real life reared it's head. you couldn't really see what I'm able to see by just looking at it. I'll attempt some more under different lighting tomorrow.

the discoloration is limited to about the first 1/2-3/4" of the blade at the toe, and is only about a millimeter deep "into" the steel it appears.

I wouldnt really be worried about the steel being overheated at this point, its done with, no sense in grinding down more steel and running the risk of the exact same thing if you get another sharpener that doesnt know what they are doing.

All in all, if the discoloration is your main beef, then try not to worry about it. The steel might be weaker, but the damage is done, but again, not much you can do a about it. Maybe take the skates in to the guy that did them and just give him a heads up that he needs to let the blade's cool a bit more inbetween passes or not press as hard.

That is probably what I'm going to do I've just decided. It's not really that bad. A few sharpenings and it'll probably be ground away.

i think I would not that guy touch my skates again though. Steel is a pretty good conductor of heat. You gotta wonder, if he heated the blades enough for discoloration and ruining the temper enough for chipping, did the heat also do damage to or weaken the holders where the plastic touches the metal near that spot?
