Customer Reviews

A suprising find.
Kevin H. on Jun 11, 2023

While scrolling through the OTF knife selection at Blade HQ I came across the PDW Audax and from the pictures, specs, and price I decided to ride to the store and check it out and I'm sure glad I did. I'm no knife expert by any means or claim to be but in my opinion, this is one of the best OTF knives for the money,premium materials,quality craftsmanship,and a fair price which I can only see increasing. I've handled more expensive top-brand models of OTF knives and own some at the same price point as the Audax but must say that most of them fall short in comparison for the money you're spending and the quality you're getting. If you are looking at getting one of these just do it when you can find them in stock, you won't regret it. As always a big thank you to the staff at Blade HQ in Marion VA for being super helpful and friendly, if you're in the area go by and check out some awesome blades.
