check out coldsteel.com knives,great knives at great prices,emerson is good but i personally think the prices are outrages for something with a g-10 handle,at that prices ide expect a titanium handle,for working outdoors i carry a coldsteel,for all around carry i take my spyderco police 4 inch model modified to open when pulled out of the pocket,i had a lanyard hole drilled into it because the stainless handle could get slippery at times,its ultra-thin plus strong and fully serrated so the edge keeps longer.benchmade is a great brand so you cant go wrong there and gerber has a few good models with quality steel like the appelgate fairbairn folder,also check out CRKT knives,battle tested in iraq,a soldier used his desert cruiser to take down an insurgent.i would suggest
http://topsknives.com/ for great fixed blades and folders,there are many knives and they are personal choices,i listed brands that i own and have used,i dont understand why smith and wesson,winchester make great guns but their knives are shit,but ide go for topsknives ,if you live in an area where you are allowed autos ide go for microtech
