Kevin, with that budget the first thing you want to do is shop online. There are numerous dealers and I will suggest a few. You will also need to purchase a means of sharpening your knife. The Mini Bushman by Cold Steel is a very good minimalist knife. It is a one piece with a rolled handle open at both ends. You can improve the handle somewhat wrapping paracord ( a usefull reserve supply) If you make up a small container of gear, you can wrap it also and friction fit it inside.
www.discount knives.com has excellent prices,service and selection of Cold Steel and many others. Scandinavian type knives often lack a guard and are more slicers than choppers. Mors Kochanski, canadian instructor and author of woodcraft books actually prefers these. Erikkson of Sweden makes a MORA2000 model with a unusual grind that actually works well, comes with a secure sheath and a hard rubber handle that provides an excellent grip. You can get one for $26 from
www.ragweedforge.com Ragnar also sells a variety of small diamond hones. A two sided unit goes for $15 and he has a flat S/H fee of $5 on all orders. There are several other inexpensive knives in that line that may appeal to you. The 2000 is their idea of a survival knife and isn't bad. Barry at Blueline Outfitters sells the A/F survival knifes @ $35. I did a review in the forum that you can search. They have drawbacks, but at that price are a fair choice.
