Ok I have the BK2 and Had the Seal Pup Elite. Seal Pup had a rock hard handle...absolutely hated it. It was slick and didnt eat up any vibration. The sheath was just ok. I didnt mind AUS8A but there are better. Knife was light and I like that size but there are far and away better! I think I would put this money aside and save it up for something better.
BK2 like it but it is so thick...blade is .25" thick! It is also heavy and I dislike the slick hard plastic handle. Wet hand, cold, shock...no! I am planning on getting some micarta scales. Sheath is nice but this knife is too thick to be well round...trust me I tried and I have had much better success with other. It is still one of my favorites but it isnt as well rounded. It is a tank but like a tank it isnt good every where.
For me a survival knife needs to be around 5" and no more than 6". Dont buy a zombie chopper either, I did and I never use it. I tried and I was soo disappointed! I can see to collect or to have one of but they are extremely one dimensional. Your not gonna prep food with it...even Fred Flintstone doesnt! They are big and heavy and not stealthy! They are extremely limited. You can baton just fine with a 5-6" blade...survival isnt a contest its about being smart! And some other advice, just because a knife can chop up cinder blocks doesnt mean you should do it nor punch holes in steel...I hate these test for they are not practical even in urban survival situation you would be foolish to dull or nearly destroy the edge of your knife on steel or concrete. If you are smart you will find other means if your situation requires you to break concrete or cut steel! I like noss but I know no one that even in a survival situation will risk their knife, you will find other means. But back to your requirements, Partial Serration...that is a preference one I can see some use for. I do like serration for something, cutting vines, rope, webbing, etc are a lot easier. I myself only have one or two blades that are part serrated. They get use! Stainless I like for if I am in the wet it is nice not to worry. Easy to sharpen depends on the edge and the steel. 1095 is easy to sharpen where as M4...oh boy...no! Hole...think about this ramboo...the gerber LMF II will suit this need but it is just an alright knife. Hammer...for tents stakes or something...my advice use a small log or even a rock it will be easier and you wont hurt your hand trying to use a small surface, more over you wont beat up your handle even break it! Once again survival is about being smart! The knife you are looking for is out there but is a jack of all trades and a master of none!! You are describing the Gerber LMF II. I have had one and didnt mind it but there were better out there. The sheath is big, sharpener was barely functional! Hammer on the pommel is meant for very light use...it will break. The 440C is fair at best! And it has holes all over it to put some 550 and tie it to a stick...once again there are far smarter things to do then throw your knife!! Especially if it is the only thing you have left. Leave that to Stallone. It works in the movies but not so great in real life! The LMF II is cheap so if you want to get it and beat it up go for it! But my suggestion is read up more get something practical. Guys like bear, Cody, Dave C dont carry very big blades in their survival situations. They do well with them and dont run into issues.
If I would recommend a blade to you I would get a fallkniven S1. It is stainless, convex grind, full tang, minimalist sheath, great grip even when wet and it eats up the shock. I have an ESEE 4, (had a 5) 6, and a Junglas, Fallkniven F1, S1, A1, BK2, BK7, Bravo 1, Nighthawk, and more. Knives I use to have where the SOG Seal Pup Elite, LMFII, Seal 2000, and more. My go to has been the S1. It is the perfect size for me. I find this size a balance. It wont do everything but its size is a sweet spot for the more common practical uses. I love it...it is over 100 bucks but I would have saved a ton of money and time if I had simply gotten an S1 and A1 in the beginning. I do love my ESEE 4 and 6 they are up there and the warranty..awesome. Every knife I have has been on one trip or another. They have all batoned, prepped food, minimum chopping (I have a Sven Saw and Trailblazer...I dont like to chop...too much energy and very inefficient...once again being smart). the S1 is a little thick for cleaning fish but it does work! I love the sheath (initially hated it) its small lightweight size is a plus, knife stays in and I wind 550 around it. Because it is small it can also be stealthy! One suggestion...the black blade will look like crap after one outting. Get the satin...I know it but you will thank me later...black doesnt stick to VG-10...a stainless steel well at all. ESEE 1095 black blades totally different story! Black is baked on and will stay on for a while! Back to the S1, I can touch it up with a mouse pad and some sand paper. It is a very good VG-10 stainless. I have not chipped any of them (Fallknivens) and they have taken a beating (more than all my other knives put together that is how much I like them!! It has been great for shelter building which takes a lot longer than you think!!! Take your time and be smart think of what you want to do with the knife and go from there. You described a survival knife so I gave you my take and experience. Good luck and I hope this helped!
). I took some 2000 grit paper from my sharpening kit and took it right off - no problem.
