For the cheap end of things , ( thats me ) the best folders I found are the Opinel and the Okapi .
The handle on the opinel tends to swell and bind in humid environments , but this is fixable / preventable , and the blade on the opinel is a bit delicate , I have folded the blade on my #10 several times , but it peens back easily enough too . The plus is it easily takes and holds a razor edge , its good for skinning and butchering , but not so great for dealing with hardwoods and stuff .
Okapi has a thicker blade , it also takes and holds remarkably well a razor edge , in my expirience , longer under the same treatment than the opinel . I regularly carve with my Okapi , and it takes days to shift the shaving edge from it .
The handle is also resin impregnated so there is no swelling and binding issue . Okapis are notorious for being blunt new , I get mine sharpened in the factory , its free , I guess its up to who you buy from tho what you get , like the Opinel , I have had some realy badly ground blades on them too as well as some deadly sharp ones .
For a fixed blade , on the cheap end of the scale , I have a reasonable bunch of Marttiini knives bought for a max of AU$25 on ebay , new . The stainless steel blades are nice , shiny , sharp , deadly sharp and seem to hold their edge OK when used for just game dressing , when they were used for whittling they seemed to blunt some , but not a lot . The carbon steel blades on the other hand , are incredible . I cant rave about them enough realy

but then if its usable and sharp , and stays sharp , and keeps on staying sharp Im easily pleased .
The only downside I found with them is the thickness of the blades can at times make using them for kitchen duty a bit of a chore , slicing veggies and stuff isnt their forte , but they do it pretty good anyway , they just perform far better doing things as cutting string rope , skinning cleaning and sectioning a carcass .
I wish I had the money to be trying out higher end knives
I should mention I guess that I dont do a lot of prying and digging with my knives , I will dig grubs out of wood and roots , but if I need a hole dug , Ill cut a digging stick ....
I learned from folk who treated a knife as THE prized possession and used whatever else they could instead of abusing their blade
