A long shot perhaps, but before going through eBay hassle....
...anybody want to swap their G10 strap on crampons (or similar, Monte Rosas or whatever) for an unused pair of old model step-in/clip on Black Diamond Sabretooth crampons?
I need a pair of C1s, walking crampons, suitable for most boots, the BDs need a front welt and a more serious Winter boot.
The BDs are in excellent condition, never been used, carried in pay pack occasionally but never worn, still have the original box. They are however a few years old now and are not the same as current versions of the Sabretooth.
The G10s or similar should be strap ons and ok with B1 bootthe they don't need to be unused just in reasonable nick.
