Tenable Leviathan B1083A3 — Stonewashed D2 Hawkbill Cleaver, Black Micarta

The B1083A3 variant of the Leviathan swaps in the most task-focused blade of the family: a stonewashed D2 hawkbill cleaver. That hooked, claw-like profile bites rope, cord, seatbelt webbing and stretch wrap the way a straight edge never can — the material pulls itself into the edge as you draw. Backed by 3.2mm of D2 tool steel and wrapped in black Micarta that stays grippy in rain, blood or fish slime, this is the Leviathan for anyone whose cutting list includes fibrous material. Daniel Sparhawk's Warhawk Knives design keeps dual deployment (flipper + thumb hole) and a liner lock sized for the blade. Compare it with the rest of the Tenable Knives family or our full knives catalog.

D2 Steel & Hardware Selling Points

• D2 Tool Steel at 58-61 HRC: High wear resistance keeps the hawkbill edge sharp through abrasive rope, webbing and cardboard far longer than budget stainless.
• Hawkbill Cleaver Profile: The curved edge excels at pull cuts — rope, zip ties, hose and packaging film practically fall apart.
• Stonewash Finish: Matte, wear-hiding surface that matches hard-use duty perfectly.
• Black Micarta Handle: Resin-impregnated layers that grip harder when wet and toughen with age.
• Flipper + Thumb Hole: Dual deployment for bare hands or gloves.
• 3.2mm Blade Stock: Serious thickness behind the edge for a folder this size.

5. Collector Rotation: The most distinctive blade shape in the Leviathan family.

FAQ — Tenable Leviathan B1083A3

Q1. Why choose a hawkbill over a straight edge?
A: Hawkbill blades concentrate force at the curve during pull cuts — they outperform straight edges on rope, webbing and fibrous material, at the cost of general-purpose slicing.

Q2. Does D2 rust?
A: It is semi-stainless. Saltwater exposure will stain it if ignored — rinse, dry and oil after marine use.

Q3. How do I sharpen a hawkbill?
A: Use a round ceramic rod or tapered diamond rod to follow the inside curve, plus a flat stone for the bevel.

Q4. Is it legal in my area?
A: Hawkbill folders are legal in most jurisdictions, but local knife laws vary — check yours before carrying.

Q5. What differs from the other Leviathan models?
A: Identical frame and size; B1083A3 is the stonewash D2 hawkbill with black Micarta. Other variants run blackwash D2, TiCn D2 or Damascus blades.

Key Terminology

Hawkbill Blade
A blade with a strongly curved, claw-like edge designed for pull cuts — the standard profile for rope, webbing and rescue work.

D2 Tool Steel
Air-hardening high-carbon, high-chromium die steel; semi-stainless, 58-61 HRC, famous for wear resistance.

Micarta
Layered linen/canvas/paper compressed in resin — grippy when wet, tough, and develops a personal patina over years.

Stonewash Finish
Tumbled matte surface on the blade that hides scratches and suits hard-use tools.

Liner Lock
An internal lock bar springs against the blade tang to secure it open; slim and one-hand closable.

Flat Grind
A full linear grind from spine to edge — efficient slicing geometry with strength behind the bevel.

Who Should Buy / Who Should Skip

Who Should Buy:

• Ranchers, sailors and anglers who cut rope and line weekly
• First responders and safety-minded carriers who want a webbing cutter on the hip
• Micarta and hawkbill fans adding a big claw folder to the rotation
• Tradesmen cutting hose, carpet and insulation on the job
• Collectors completing the four-blade Leviathan series

Who Should Skip:

• General users who mostly slice cardboard and food — a straight edge is more versatile
• Minimalist carriers; at 8.22oz this is a work knife
• Anyone who will not maintain a semi-stainless blade in wet climates
• Users in areas restricting curved or claw-style blades

Care & Maintenance

1. Rinse off salt and sap, then dry and oil the D2 blade after wet jobs.
2. Sharpen the curved edge with a round ceramic or tapered diamond rod; flat bevels on a stone.
3. Blow lint out of the liner lock channel; debris causes sticky lockup.
4. Oil the pivot lightly every couple of months for crisp flipper action.
5. Wash black Micarta with mild soap; it needs no oils or conditioning.
6. Check body and clip screw torque occasionally — heavy use loosens them.
7. Never twist the hawkbill sideways under load; the curve is for pull cuts.
8. Store dry, lightly oiled, away from leather sheaths for long periods.
9. Inspect the edge for rolls after contact with metal; D2 resists but is not immune.
