Cold Steel 92FK FGX Kerambit-fixed Blade Knife.
Was sceptical at first, being a plastic knife and all.
Now I love it! It has a purpose and is not ambiguous about it at all!
A great way to experience the Kerambit before committing to the "Real Deal"
Very good and fast to be delivered
Received my fragrance! Very happy and would definitely buy again from this shop

This AKSA AK21 is an incredible replica. Initially, I struggled hard with it—every attempt to chamber a round resulted in a severe Failure to Feed (FTF). I hadn't even fired a shot yet and was ready to pack it up for a return. After discovering it just needs to be aggressively snap loaded, it feeds perfectly. Definitely recommend
Best price anywhere on the internet. Speedy delivery
Quality products and excellent turn around time.
