Excellent knife on all counts…. Recipient was very pleased… Make somebody happy and buy them this knife… Review: What an awesome blade! Sheath sucks though - I love this thing! I've used it for everything from food prep to bushcraft and fishing. It holds an edge for a very long time and the handle is super comfortable. My only gripe is the sheath. For the price you pay, it should come with a belt loop or some way to carry it but it doesn't. Also, the little tab you have to press to unsheath the knife feels like it may break after a hundred uses or so. That being said, I still believe that this knife is worth a purchase ## Features - QUALITY: Sheepsfoot style blade made of CPM-MagnaCut steel with partial serrations for cutting lines, ropes, and bait, the Undercurrent is a cinch to clean. - COMFORT : A composite of vulcanized EPDM rubber and thermoplastic, this durable, molded material provides a sure grip in all conditions. - YOURS, FOR LIFE: Benchmade will re-sharpen your knife to a factory edge for free, for the life of the knife. Benchmade LifeSharp services includes cleaning, oiling, adjustments, and re-sharpening. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D1RL6CJR | | Age Range Description | Kid | | Age range (description) | Kid | | Best Sellers Rank | #131,407 in Sporting Goods ( See Top 100 in Sporting Goods ) #54 in Camping Fixed-Blade Knives | | Blade Edge | Sheepsfoot | | Blade Length | 4.3 Inches | | Blade Material | CPM-MagnaCut Steel | | Blade Shape | Sheepsfoot | | Blade Type | Sheepsfoot | | Brand | Benchmade | | Brand Name | Benchmade | | Color | Depth Blue | | Customer Reviews | 4.7 out of 5 stars 15 Reviews | | Hand Orientation | Ambidextrous | | Handle Material | Santoprene | | Included Components | Knife | | Included components | Knife | | Is Product Cordless | Yes | | Item Length | 9.43 Inches | | Item Shape | Rectangular Prism | | Item Type Name | Benchmade - UNDERCURRENT, FB, SANTOPRENE | | Item Weight | 5.38 Ounces | | Manufacturer | Benchmade | | Model Name | Undercurrent | | Model Number | 18040S | | Model name | Undercurrent | | Number of Items | 1 | | Part Number | 18040S | | Product Care Instructions | Hand Wash Only | | Recommended Uses For Product | Camping, Hiking | | Recommended uses for product | Camping, Hiking | | Reusability | Reusable | | Size | 4 بوصة | | Special Features | Benchmade Knife | | Special features | Benchmade Knife | | Style | Undercurrent 18040s | | Theme | Outdoor Adventure | | UPC | 610953207946 | ## Product Details - **Age range (description):** Kid - **Brand:** Benchmade - **Model name:** Undercurrent - **Recommended uses for product:** Camping, Hiking - **Special features:** Benchmade Knife ## Images ![Benchmade - Undercurrent 18040S Outdoor Knife with Depth Blue Santoprene Handle (18040S) - Image 1](https://m.media-amazon.com/images/I/61hgXweA6ZL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent *by J***N on 10 May 2026* Bought as a gift for a friend who invited me up to Alaska to fish.
