Easily my S tier tool
Brandi K. on Nov 25, 2021

To be honest, when I first saw this knife in the case at my local army/navy store I thought it was stupid. Fast forward 6 months and its become an indispensable tool for me. From breaking down wood pallets to ripping staples from target stands it really does it all. I've used it as a screwdriver, hammer, pry bar, and it's wicked sharp to boot! Whenever I encounter a task my first thought has become "Boost?" I'm so glad to own it, and I'm truly sad they discontinued this model. I hope Benchmade releases a new one soon but until then, it's me and my Boost!

tough as nails and sharp as hell!!

I love this thing! I thought the blunt tip was gonna be annoying but its taken everything I've put it through so far and does not disappoint. Super sharp edge incredibly tough steel.
