Old sharpening grinder...

[PDXDave]

So I'm back after a bit of break with another scrap yard rescue.
Someone dumped this old Intedge sharpening specific grinder.

It runs perfectly and the bearings are nice and smooth with no rough spots or run out.
It came from a cutlery shop that was in downtown Portland for many many years.

As near as I can tell, the company was known for their kitchen knives and not tools at all, so I'm thinking it's probably built by someone else to spec and re branded.

Any information on this old guy would be helpful.

Thanks!

Damn what a nice piece.

Thanks.
It never fails to amaze me what people throw away...
The scrap value was three bucks, so obviously I'm giving it a home.

Not sure why that replied twice...

Looks like an old USA made Doerr.

Never seen anything like that double wheel guard.

That’s not a lot to fork out for a knife sharpener.

Snerk.

A little googling around implied it might used be for lapidary work.

3450rpm seems kinda high for knife sharpening.

Indeed.

I had the same thought, but knowing where it came from most definitely cements it's history.

They did a lot more than cutlery, but it's hard to say how this particular piece was used.

I don't see any means of setting angles/supports for sharpening.

Lapidary (rock polishing) grinder.

There's one on ebay right now.
