VG10 Super Steel Balisong Butterfly Knife – Glass Lizard, Kamagong Wood & Brass Handle | Authentic Filipino Balisong BF-50

Glass Lizard Balisong Butterfly Knife (BF-50)

Named for the legless lizard that sheds its tail to escape — deceptive from the first glance. The BF-50 glass lizard balisong butterfly knife is hand-forged in VG10 Super Steel on the traditional Batangas pattern in the Philippines, by smiths working the way balisongs have been made for generations.

Blade & Steel

This blade uses VG10 super steel. The vanadium refines the grain, the cobalt adds toughness at hardness, and the 15% chromium keeps rust off it. At around 60–61 HRC you get an edge that bites cleanly and stays that way — a genuine step up from standard stainless.

Handle, Bolsters & Balance

The inserts are kamagong — Philippine ebony, one of the densest hardwoods in Southeast Asia and the traditional material for Batangas-made balisongs. It is heavy for wood, close to non-porous, and it darkens with handling, so the handles you carry for a year will not look like the handles you unboxed. 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 6.53 oz (185 g) it lands in the middleweight band, which is where most experienced flippers end up. There is enough mass to carry momentum cleanly through a rollover — the handle finishes the arc for you — without the swing feeling slow. If you have no strong preference yet, this is the weight to start from. 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-50 suits anyone moving up from a mass-market balisong to a genuinely hand-made one. 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

Wipe the blade dry after handling and put a drop of light oil on each pivot every few weeks. 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.
