I could have used then I renovated my downstairs bathroom. i "sharpened" one blade with a Dremel so many times the blade was half its original length. Since only the original leading edge is hardened I had to sharpen it a lot.

Oscillating tools are very handy, but the cost of blades is outrageous. The tool is about. $50 (US) but, it looks just like multiple grinding wheels. The question becomes, how to you keep the wheels in proper shape?

They don't use wheels. The blades are not bad when you consider how much time and material they save. I repaired a spot where a hole had been cut for a staircase in the 70s. I couldn't recover enough good red oak original flooring and make it not look goofy (it was not centered or square), so I pulled out a larger area of flooring, using my oscillating saw to cut precise sections out stagger the new boards into the existing. I used a Menard's house brand metal blade to cut through the nails and a brand new Milwaukee blade made for hardwood to cut the existing flooring (I used a chop saw for the new flooring). I have three Nextec multitools, but since the blades are so easy to swap I usually only used one tool. There were a few times when my cut was off a hair, so I swapped on the diamond burr blade and sorted it. Then back to the saw blade.
The cost of the new blade paid off by reducing the number of boxes of new flooring I had to buy.

I fully understand the utility of oscillating tools. Like you, I sharpen blades many times.

My comment was in regard to that sharpening tool. I have never seen one before. If it is a stack of grinding wheels, those wheels would very quickly loose their shape. Then how do they deal with course vs fine tooth blades. I just wonder how that sharpener works,

I did some casual research on these some time ago, and you are correct. It is basically a stack of spaced 3" grinding or cutting wheels for making new teeth without regard to how fine or coarse the blade originally was. The teeth have no set after being ground this way.

Keeping the wheels true is certainly an issue. It may be good enough for field work to just get a job done. Beyond that, it seems that this sharpening tool is only slightly less disposable than those ridiculously expensive blades.
