Got This for My Brother and Now I Need OneSo my brother has been talking about OTF knives for like a year and I honestly had no idea what he was even talking about until I started looking stuff up. Saw this SOG Pentagon and thought the all black look was cool enough to justify the price for his birthday. He opened it and his eyes literally went wide... the thing just FIRES out. Like the sound it makes is so satisfying lol. He kept flicking it open and closed for a solid 20 minutes at dinner. He says the S35VN steel is apparently really good stuff (im taking his word for it) and he was impressed its made in America. The dagger blade style looks straight out of a movie. Only thing he mentioned was the box it came in was kinda underwhelming for what you're paying, but whatever, the knife itself is awesome. Now I'm looking at getting the FDE version for myself... my wallet hates me.
Looks absolutely badass in all black
Packaging could be nicer for a $200+ knife
