5 out of 5 Very Happy with Service and Knife Quality
Colt 4570 (verified owner) –
Happy with the quality of the Viper Orso. I also enjoyed dealing with the Collector Knives site and staff, especially after receiving a poor sample of the knife from another retailer. I would buy from Collector Knives again. I really like the blade shape and the crowned spine on the Orso, along with the smaller flipper tab.

First time buying from CK and was not disappointed. Order was shipped promptly and arrived on time. Knife is a great example of the model and I can’t complain about it in any way. My only issue is that now I feel I must buy the carbon fiber version of the same knife!
