Probably got discouraged from 1/2 the posts being negative towards him. Also not everybody has as much free time as we do to respond to every post in a started thread. Though they are right. Every couple of days there is a new thread about "which knife <$50. Everybody was new here at some point and not everybody has been on other forums so they might not know how everything works or where to look for the info desired. This was the first forum I ever joined (well second, forgot about glockpro though i maybe have five 5 posts there and that was after I figured out how everything works here.) What sealed the deal of members getting sickk of this is when they don't even take the time to list their specifications and expect people to respond.
Here's some primo knives under $50 new.
Folders: Cold Steel Recon 1 , Hold Out 2 , any other of their lock back folders
Kershaw's with Sandvik or S30V Steel(I really like my Kersahw storm)
Buck Vantage Pro and Avid (Hard to find at the moment though)
GEC 99 (Generally around $50)
Leatherman Sidekick
Benchmade 551 556 $65 with a coupon code at some online stores and recommend either more than any other listed.
Check the exchange here when you can. If you don't mind buying used knives you can get some great deals. Or new or lnib for that matter.
Fixed: Cold Steel GI Tanto $19
Get a Becker
Spend a little over $50 and get a Becker
Look for a used Becker and get a Becker
Seriously get a Becker
Good luck choosing OP. There are lots of good blades under $50. Though more bad ones IMO. Would avoid SOG, CRKT,Junglee.
