What Benchmade says:
The Undercurrent is your reliable fixed blade for hard-use utility while on the water. Featuring a sheepsfoot style blade made of CPM-MagnaCut steel with partial serrations for cutting lines, ropes, and bait, the Undercurrent is a cinch to clean. Complete with a Sonar Gray molded sheath that mounts on your belt, pack or boat, with push button retention release for quick access, the Undercurrent pulls you in with simplicity and performance that can't be matched.

CPM-MagnaCut Super Stainless Steel (60-62 HRC)
A new stainless tool steel with a combination of toughness and edge retention with excellent corrosion resistance and strength.

Santroprene
A composite of vulcanized EPDM rubber and thermoplastic, this durable, molded material provides a sure grip in all conditions.

Modified Sheepsfoot
The spine of the blade rolls into a curved cutting edge. This blade is ideal for rescue situations allowing the user to cut through material with less risk of accidental piercing.

Quinn Knives' take:
While the Undercurrent is marketing as a water specific knife, there is no reason this can't be your go-to heavy-use outdoor fixed blade. We especially like the retention feature of the sheath, making this a knife you can take out on adventures with full confidence.
