not sure what you mean by "similar"- size, hilt, steel, sheath, function, so will start with generalities.

Mora make many many solid knives starting at $10.00-15.00
solid, many handles, many steels. Not a big fan of most sheaths

Cold Steel has several (such as the Finn Bear) at 12.95 with Cordura Sheath. Good brand, good reliability overall.

Columbia River Knife and Tool has a great variety under 50.00

No affiliation blah blah- but knifecenter.com has large selection, reasonable prices. Go to fixed knife section (http://www.knifecenter.com/knifecenter/index/hunt.html) and hunt-

either by brand, type, or steel type (steel or carbon)
