Spyderco Native S30V sold at Wal-Mart - I know it's been mentioned but this is a great deal. Premium blade steel with Spyderco quality for under $40!
CRKT Ryan Plan B - Available
here for $12.
CRKT M16s and M21s - Aluminum versions of the
M16 are available around $40 with AUS8 blade steel. They are a great deal. The titanium M16s are slightly more expensive but they're made of titanium!!! They still can be found for around
$70. The M21s can be found in aluminum with AUS8 blade steel and awesome blade ergos for
$40.
Victorinox SAKs - I've found many of these on sale at Lowe's but I've heard they're discontinuing much of their knife selection. I've bought several clampacks that contained a Rally and Climber for $5 ea. I've also seen SAKs packaged with mini Maglites as well as others anywhere from $5 to $10. I don't guess you could say these are good deals since they happen sporadically but I thought they were still worth mentioning.
