These are tough, simple ice tools. Not the sort of thing you use for super steep ice overhangs, but perfect for a route like the West Rib of Denali, where you might have short sections of steep ice, swinging both tools, followed by long stretches of mixed rock, dirt and snow, where you might use these as an alpine axe, driving the shaft in for balance. They are bent shaft (that's not a defect!) but not so bent that you can't use them to self arrest. A bit heavy and clunky and the metal shaft get's really cold. But you can also use them to beat bears away in a pinch.
I don't think Black Diamond even makes these anymore, so I can't say what they retail for new. However the closest substitute is probably the Black Diamond Venom, or the CAMP Corsa, which sell for about $130 each. These used tools, moderately beaten up but in great condition, are $90 together, $45 each.
