Tenable Kitpu B2123A5 Water Ripple Damascus Blade Amber PEI/Ultem Handle Liner Lock Folding Knife

The Tenable Kitpu B2123A5 is a slim gentleman's folding knife inspired by the Mi'kmaq word for "eagle." Designed by Jonathan, a Newfoundland-based knife maker and lifelong outdoorsman, this blade merges functional art with everyday practicality. The 2.90" blade comes in premium Nitro-V or Damascus steel. Nitro-V delivers superior corrosion resistance and edge retention for daily use, while Damascus offers a distinctive pattern with enhanced durability and collector appeal. The handle is available in multiple materials including the lightweight, temperature-resistant PEI option featured here, ensuring a secure grip and refined aesthetic. Deployment is effortless thanks to a minimalist back flipper tab with ceramic ball-bearing pivot, enabling smooth one-handed opening. The liner lock mechanism provides reliable blade security during use. The reversible deep-carry pocket clip allows both right- and left-handed carry, while keeping the knife's profile clean and pocket-friendly. Compact and lightweight, the Kitpu excels as an everyday carry (EDC) knife, balancing portability with performance. Nature-inspired design philosophy and meticulous craftsmanship make this blade a versatile companion for outdoor enthusiasts and knife collectors alike.

Damascus Blade Introduction

Damascus steel is renowned for its distinctive wavy patterns and exceptional combination of strength and flexibility, offering superior edge retention and resilience against chipping. However, its layered structure renders it prone to corrosion if not meticulously maintained, and variations in modern forge-welding quality can lead to inconsistent performance. Regular oiling and careful drying are essential to preserve both its aesthetic allure and functional integrity.

The Kitpu B2123A5 runs a Water Ripple pattern-welded Damascus blade: forge-welded layers etched into concentric ripples that no two blanks repeat. The steel takes a keen, fine edge with good toughness, and the etched surface hides carry wear gracefully. Damascus wants one habit in return - dry it and oil it after wet work - and it will patina into even deeper character. Paired with translucent amber PEI/Ultem scales, this is the family's showpiece.

Glossary of Key Terms

Damascus / Pattern-Welded Steel
Layers of differing alloys forge-welded, folded and acid-etched so the boundaries show as flowing lines. Strong, flexible and unique per blade, but it wants routine oiling.

Water Ripple Pattern
A Damascus layering style etched to read like concentric ripples on water - no two blades come out the same.

Acid Etch Finish
The chemical bath that darkens the softer layers and makes the Damascus pattern legible.

Wharncliffe
A perfectly straight cutting edge with a spine that slopes to meet it at a low, fine tip - the most controlled push-cut profile there is.

Crossbar Lock
A spring-loaded bar spanning the handle that wedges against the blade tang - fully ambidextrous and among the strongest folder locks.

Lightning Strike Finish
A titanium surface treatment that looks like branching electrical discharge; it is etched into the metal, not printed on it.

Tenable Kitpu B2123A5 - Who Should Buy / Who Should Skip

Who Should Buy

• Office carriers who want premium materials without a wallet-draining price.
• Left-handed users - the reversible deep-carry clip and liner lock work either side.
• Fans of Jonathan Styles' Tenable designs at an entry-level price point.
• Anyone who values light weight - 2.5 oz is a true all-day pocket knife.
• Gift buyers who want a named designer folder under a hundred dollars.

Who Should Skip

• Anyone needing heavy prying or batoning - the slim 3.2 mm blade is a cutter, not a lever.
• Users who want super-steel edge retention; Water Ripple Damascus trades some wear resistance for toughness.
• People who dislike flipper tabs on the spine of a classic-styled folder.
• Buyers in areas restricting locking folding knives - check local law first.

Tenable Kitpu B2123A5 - Care & Maintenance

1. Dry the blade immediately after every use - the layered welds of pattern-welded steel trap moisture at the etch lines.
2. Keep a thin film of mineral oil or camellia oil on the Damascus surface; reapply after any wet or humid day.
3. Never let food acids, salt water or blood sit on the etch - they darken and pit the pattern permanently.
4. Clean with warm water, a drop of mild soap and a soft cloth; avoid abrasive scouring pads on the etched face.
5. One drop of oil at the pivot and lock face monthly, then cycle the action a dozen times to distribute it.
6. Blow lint and grit out of the handle channel with compressed air before oiling the pivot.
7. Touch the edge up on a fine ceramic rod or 3000-grit stone; light, consistent passes preserve the layered edge.
8. Store it dry and open, out of any leather pouch or sheath - tanning acids and trapped humidity attack the weld lines.
9. Re-torque clip and body screws with the correct Torx bit; never use a worn flathead on precision hardware.
