Iím sorry to be lateÖ tico seems to be right.
The Blitz were marketed by CASSIN (Italia) and created by Martin Gutsche in 1987 .
Some more info: Patent DE 37 17 027. 8 December 1988. In the Cassin catalog 1991, the Blitz are numbered as #1, #2 and #3. Lighter than a SLCD of a similar size. The color anodized part must be placed upside, the non anodized part being downside.
Steve, your prototypes with coil springs are superb!

Anyone got a pic of these in a crack?

How did they work? I can't (cough, cough)remember?

The small one on the left is as it would be situated in a crack. When loaded, the hitched sling draws the mobile ends toward each other and the scissor action provides the holding power.

The design flaw in a parallel placement is that the load transfer in a shock loading situation is too quick to allow the mechanism to bite and maintain its position. Loading in a conventional cam is prompt and direct.

J says "yes".

I can't remember the OP or the conversation that led to it at all.

Perhaps the answer wafts around in one of the Smokin' Partner threads?!? LOL
