Schrade made some really nice knives, I've only got a couple of them since older US made ones are hard to find in Argentina. But they've all proven to be solid users so far.
What you've got there is, as CA357 pointed out, a "Bear Paw". The model number is LB7 (sometimes with a couple more letters for different handle materials, for example LB7ST for stag and so on). You'll find more information searching for "Schrade LB7" since knife guys tend to prefer model numbers (I don't know why "Bear Paw" is easier for me to remember).
I'm not a Schrade collector, I just like them and use them. So I can't give you a whole lot of info. But here's what little I know about your knife. The LB7 was first introduced in a 1979 catalog as part of their Uncle Henry line up. (apparently there were some available in 1978). Yours has four pins through the wood scales, that means that it probably is one of the older ones. Schrade switched to three pins around 1981. The blade was made out of "Schrade +" stainless steel (they used 1095 high carbon steel on some knives as well), which in my experience works more or less like Buck's current 420HC. Not a super high end steel, but practical as hell.
Here's a little booklet that Schrade used to include with their knives. I loved this company, their Uncle Henry knives had a 1 year loss warranty! What kind of company will replace a lost knife for free?
Nowadays, unless they're mint (with box and paperwork), or a really rare model, Schrades don't fetch a very high price on the collector market. A good thing, IMHO, these knives were ment to be used. Good tools at a good price, turning them into expensive collectibles would be against their spirit.
Here's my favourite Schrade, I got it NIB a couple of months ago as a gift and I've been using the hell out of it.
