I had heard of them previously... Back in the early '70s I bought Ice Crampons made by them. I still have them in a box with my Jon_E Handwarmers! I'd also seen some of their tools at various exhibits in the Hudson Valley.
I used the crampons a number of times in the Catskills on winter hikes and on over night backpacking deer hunts. Over the years I acquired various other options... things like IceBug boots that have car like carbide studs in the soles. They suffice for what I do... I'm not climbing frozen water falls or other such nonsense at this point in my life.
I've worn the IceBug boots while riding my Schwalbe Ice Spiker tire equipped bicycle on ponds during ice fishing derbies.
P.S. I just found a pair on E-Bay... I'd not buy from that guy after insulting me with the line "They are a great addition to any antique collection or could be used." I bought them new! LOL
