From the moment I saw the SOG SEAL XR in the SHOT show video I was interested. I have always liked a stout knife and have had many of them, from tons of different manufacturers. This one is big and not for the faint of heart but those who like overbuilt knives will love this knife. Blade length: 3.82" Blade thickness: .186" OAL open: 9.13" OAL closed: 5.311" Blade steel: s35vn I have carried this SEAL XR non stop since I got it over 1 month ago: First and foremost, this goes without saying... the knife is an absolute tank of a knife. The blade is .186 thou thick, but do to its high grind it maintains a very usable cutting geometry: For those wondering, its handle is .696 thou thick and fills the hand well. There's jimping all over the place that definitely isn't needed, but I have not sanded them down and I have used the knife pretty darn hard without any real pain or blisters. Here's some action shots of the knife cutting thick hoses off of fittings and making short work of clear vinyl: I cut 12 of those hoses from those fittings, they were extremely stubborn to come off once the clamp was released, I used the knife to completely cut down to the fitting and they came right off. This leads me to my next point I'd like to hit on, the heat treat is DAMN good, like really good. I absolutely love their heat treat on this hunk of s35vn. I haven't seen a single chip of any sort despite my rather hard use/abuse, and it sharpens up SO nicely... holy batman, it gets retardedly sharp. I can make this edge make hair pop off with barely any effort on my dmt stones. I will say, the steel they used for the liners and extended pommel are a carbon steel that rusts easily when wet. I had the knife clipped to my shorts while lounging in this river for about and hour and rust was all over the liners and extended pommel/crusher. Sorry, didn't take pics of the rust before I cleaned it. Overall this knife is a keeper in my stable, it's a rugged knife that is smooth as butter and cuts surprisingly well (obviously compared to an opinel on a zucchini this is a brick) and is well worth the price. (For the sake of disclosure, I attempted to purchase this knife before it was released and SOG sent me this knife for free, despite repeated attempts to pay). For those who know me, if this knife sucked I'd say so LOL Well done SOG, the only complaints I have are the jimping which I can live with (if I couldn't I'd sand them down) and the components that rust very quickly if wet. That said, everything cleaned up nicely and if you maintain your knife, is no big deal. I actually nearly forgot, I did knock some of the jimping on the flipper tab down... Hope anyone who may be interested in this knife finds this helpful.
