Here's a few relatively small blades from my collection:



From the top down...

Buck/Hartsook Ultralight
$40.00 msrp

Benchmade 10610 Benchmite II
$35.00 msrp (Discontinued)

Spyderco Dragonfly Stainless Steel
$89.95 msrp (FRN handle version $69.95 msrp)

Case Mini-Blackhorn
$9.95 @ Lowes Hardware

Cutco Pocket Knife (DD serrated edge version)
Price varies from your local Cutco seller.

Gerber Curve (Blue)
$13 msrp
*In addition to the locking knife blade, it has three screwdrivers, a nail file, and a bottle opener/spring clip.

For a size comparison, the bottom knife is a common Victorinox Classic keychain knife.

Thought it worth mentioning that the Case Mini-Blackhorn is one of my favorite knives. It's under $10, it's made in the USA, and it's a great size, shape, and blade profile for daily use. Plus it weighs next to nothing. I've given away a bunch to friends and family over the years and they've held up quite well.
