Viper Strike?

Anyone used it? How about fit it to a charlet tool? Looks far more steamlined than the grivel trigger.

I have it on my Vipers and it's great for matching and protecting your fingers, but that may not answer your question.

I installed viper strikes on a pair of aztars when I couldn't get access to the charlet griprest (quark). It took some futzing and whitling to make it happen, but they function well enough. it doesn't leave much spike exposed, which may be an issue if you hope to use the tool for alpine climbing...
