Spencer R.wrote a review of Petzl Spatha Knife on June 2, 2019
Familiarity: I've used it several times
Works fine as a knife, locks open, serration is great for cutting cords, lightweight. Kind of bulky on the harness, feels cheaply made, expensive doesn’t open one-handed. If you want a knife that disappears on your harness get something like the Trango piranha or one of the small CRKT folders which can be stored in the ice clipper slots. The Pretzl knife requires its own carabiner which negates any weight savings the plastic handle provide, and it takes up room on your harness. Works best clipped to your haul loop.
