D2 Tool Steel Balisong Butterfly Knife – Rosewood & Brass Handle | Authentic Filipino Balisong BF-105

D2 Balisong Balisong Knife Bf-105 (BF-105)

The BF-105 d2 balisong balisong knife bf-105 is hand-forged in D2 Tool Steel on the traditional Batangas pattern in the Philippines, by smiths working the way balisongs have been made for generations. Part of the Filipino Traditional Series, which follows the Batangas pattern that defined the balisong long before it ever left the Philippines: sandwich construction, hand-fitted inserts, and a latch that seats with an audible click.

Blade & Steel

D2 tool steel makes up the blade. Originally a die steel, D2 carries a heavy carbide load that translates directly into edge retention — this is the alloy to pick if you want to sharpen as rarely as possible. At 58–62 HRC it is hard, it is abrasion-resistant, and at roughly 12% chromium it resists staining without being fully stainless.

Handle, Bolsters & Balance

The handle is natural rosewood — dense, naturally oily, and warm in the hand in a way synthetic scales never manage. It polishes to a deep chocolate-and-rust figure and needs nothing more than an occasional wipe to stay looking new. The frame around them is brass, which sets the knife’s weight and gives the inserts something rigid to sit in.

How It Flips

At 7.76 oz (220 g) this is a substantial knife, and it flips like one. The extra mass smooths the arc and makes openings feel deliberate rather than snappy — you are steering momentum instead of generating it. Flippers who like a knife with presence in the hand tend to prefer exactly this range. The brass in the handles pushes the balance point outward, which steadies the swing further and is why brass-handled balisongs feel calmer in the hand than their weight alone suggests.

Open, it measures in the compact-to-standard Batangas range — the size most Filipino makers settle on, and the size that suits the widest range of hands. Large enough to feel like a real knife, small enough to carry comfortably.

Specifications

Every knife is finished by hand, so dimensions and weight may vary by roughly 3–5%, and natural handle materials differ piece to piece. Yours will not be an exact twin of the photograph.

Who This Balisong Is For

The BF-105 suits flippers who want a real Filipino-made knife without going into custom territory. It is a working knife rather than a wall piece — it can be carried, flipped and sharpened — but the fit and the handle material make it a legitimate display piece too. If you are buying a gift, this is the price bracket where a balisong stops feeling like a novelty.

Care & Tuning

Keep a light film of mineral oil on the blade, wipe it dry after every session, and never store a carbon blade in a leather sheath long-term — leather holds moisture. If the handles develop play, seat the knife closed and tighten the pivot screws a quarter turn at a time until the play disappears without the action binding. Zen pins and tang pins can be dressed with a fine file if the handles start to strike the blade — do this a few strokes at a time.

Live blade, sold to adults 18 and over. Customers are responsible for knowing and complying with the knife laws that apply where they live.
