Multi-tool.
One of our members, a buddy of mine, retired Army that has been there and done that from blistering hot, to sub-zero temps informed me:
"If I had to go into combat today, right now, and do what I had did, I would not take a knife, instead my Leatherman Super Tool".
He looked at me as we were heading down the road, to see my reaction.
He knew I had little experience with multi-tools. I had shared I had won some in shooting, and never really used them, and do not know what happened to them.
He is familiar with some of what I have done, some of my lessons, and mentoring, and knives used.
"You are bit crazy, about some minimal stuff you have done, not a bad thing, actually good, still some is borderline crazy and some is flat out crazy".
We have different backgrounds, life experiences and all, and we agree to disagree.
Simply because, we have not done what the other has, so we learn from each other.
So he gave me a Leatherman Super Tool.
I understand this one is no longer made, and I forget which model took its place in the Leatherman line.
So I used this Super Tool for all sorts of uses, just as I might in survival situations.
I used it in my kitchen for food prep, to doing home repair, fixing electrical, plumbing, engine (lawn mower), cutting down small trees, I needed to cut down.
I do mean small trees, along with smaller hedges and shrubs, and I had a huge brush pile when I was done. It shocked my neighbor I did all that with a Super Tool.
Now this member has used GI Demo knife, Victorinox Soldier, K-Bar, Bayonets, and a custom fixed blade he showed me, plus some other knives, and I think one included a Buck 110.
Still when he said he would take a Super Tool into combat, and want it for survival needs, I paid attention and listened to what he had to share.
Define "survival" , it can and does mean different things to different people.
I always wanted a pair of channel lock pliers when I was out and about...and have used these with a pocket knife or fixed...
Another friend always wanted Vice Grips in addition to his ~ 4" carbon steel Stockman pocket knife
He too has been there, done that all over the world.
Yet another refuses to be without a Victorinox Farmer.
Yeah, I miss my Farmer, and is another knife on my list to replace.
I have spent 14 days in Canada , canoeing and portaging with nothing but a Case Peanut, yellow handle with CV blades.
Same knife I took a 5 day survival dealie mentors had me do.
Boker Tree Classic 240, with Rosewood handles, which is a pen knife about 3 1/8" closed length with carbon steel blades is another knife I have used in "lessons" , "set ups" and in real life when I had to use, what I had on person.
Someday, I would like another of these, if they can still get this knife in the US.
Case yellow handled with CV blade Slimline Trapper is another old friend of mine that has been with me and been used for...name it I have used it for it, including stopping a threat. Case Sodbuster Jr is another.
Multi-Tool is another tool in the toolbox, and again I pay attention to what some folks share with me, as they have been there and done that.
Hence the reason I still use this Super Tool gift to educate myself and get some skill sets with a new to me tool.
I don't have a sheath for mine, I instead sometimes use a shoe lace for lanyard, and have in my pocket.
I was mentored to have a knife in pocket, as sheaths can lose folding and fixed blades, when serious situations occur.
Always always always have a knife of some kind in your pocket. You never know when that is all you have to work with , the items in pocket.
