Re: Excellent choice for survival knife would be??????
For that kind of money, you can buy all but the higest end custom blades. But keep in mind, a "survival knife" is the one which you have on you at the time. Not the one cached at home with all of your other gear.
Edge retention & ease of sharpening are sort of at odds with each other. Usually a knife that's easier to resharpen wont hold an edge quite so long as one which is harder due to the steel used in its manufacture, or its heat treatment.
While it's trendy, & written about much, unless you live in the surf zone without any time to care for your knife, coated stainless steel is over rated. And has more vices than virtues, at least in fixed blades.
Go to
www.mdtactical.com & look up what Kevin's written about choosing a knife, & knife materials.
It would pay to do some perusing of knife websites, as well as some catalogs like Brigade Quartermaster & the like. Then you'll have something of a picture as to what's out there, & what you might like.
Also keep in mind, don't buy anything more expensive than you can afford to lose or break. Such things do happen in FUBAR scenarios. And it's also wise to carry more than one knife if you really anticipate depending heavily upon them.
Like say a good fixed blade, & as a supplement, a folder, swiss army knife, or multi-tool. The latter being real handy.
No one knife excells at every sort of task which comes up, & most wind up buying one far larger than they really need. Which winds up being less utility oriented, more to carry, & more to sharpen.
Just like a good holster is a necessity for a sidearm, as a good sling is to a rifle, a good sheath is indespensible. Or a good pocket clip on folders. Staying attached to one's blade is sort of vital, even if it means a piece of dummy cord with a small carabiner on it/or some form of retention lanyard.
Google Don Paul, & see what he's written. His advice on knives, while a touch dated when last I checked, as far as blade makers, is still very valid & practical.
It's the tool above the neck which will keep you alive, warm & fed ultimately.
