Skeleton Key? I think there was a thin and a thick version.
The Culti or the MBC def fit but may be a bit harder to find.
The Mini Mean Street is .145 - 7.8 OA and came out after this thread was posted should work great. If you can go a little bigger I'm loving the new Park Ranger at .145 - 8.4 OA and there should be a few of both on the exchange.
.090 Elmax is the Scrapmax line.
The Mini Mean Street should be right up your alley, and they have been available on the exchange about once every two weeks. But I am sure you will get a PM today or tomorrow if you put up a WTB ad.
The BAD is a nice option, thin, hard and INFI, but they are a bit pricey, being north of $400 in most cases.
The Scrapmax line has a longer handle, but being a stick tang, they can be removed and modified to perfection. For now, I just reshaped my handle since I found the factory configuration to be a bit too blocky.
I also grabbed a Park Ranger and I am loving it, now that I changed the handle on that too. Just took the hump on the rear corner down a little.
The Busse Steak Knife came in 3 blade lengths, the shortest being 3.5" with an 8" overall length. The steak knives are made with .090" thick Elmax and the blade is hollow ground – they are great slicers!
