A different direction for TRM, built with the same precision.

The TRM BULLDOG Rev. B takes TRM’s reputation for clean design and pushes it into a more robust, full-hand platform. Paired with 3D contoured titanium Lizard Skin scales and the River-Lok, this is a knife that feels more substantial while still maintaining TRM’s attention to detail.

It’s a natural evolution for those who want more presence in hand without giving up refinement.

A Legacy Built on Titanium

Before TRM became known for knives, it was known for titanium.

In 1997, Les and Marianne Halpern started with titanium scraps at their kitchen table. That small operation grew into Halpern Titanium, one of the most trusted manufacturers of precision knife components in the industry.

They’ve produced millions of parts for major knife brands.

That experience carries directly into the BULLDOG.

River-Lok System

The River-Lok is TRM’s take on an ambidextrous bar-style lock.

• Smooth, controlled action

• Strong, secure lockup

• Easy to operate from either hand

It’s designed to be intuitive, reliable, and practical for everyday use.

3D Contoured Lizard Skin Titanium

This version features fully contoured titanium scales with a Lizard Skin pattern.

• Organic texture that adds grip and visual depth

• Contouring that fills the hand more than slimmer TRM models

• A premium feel backed by real machining experience

It’s a combination of comfort and detail that stands out.

MagnaCut Performance

The blade is made from CPM MagnaCut, delivering:

• Excellent edge retention

• Strong corrosion resistance

• Toughness for real-world use

It’s a steel that matches the BULLDOG’s more substantial design.

Built for Real Use

Compared to the ATOM and NEUTRON, the BULLDOG brings a bit more presence.

• Fuller grip in hand

• More substantial feel without being oversized

• Still carries clean thanks to TRM’s design approach

It’s a great option if you want something a little more robust in your rotation.

Made in the USA

TRM builds their knives in Massachusetts, continuing a legacy that started at a kitchen table and grew into one of the most respected names in titanium manufacturing.

Why This One Stands Out

The BULLDOG Rev. B expands what TRM offers.

It keeps the precision and material quality they’re known for, while adding a more substantial feel and an ambidextrous lock system.

And the ability to reverse the clip for left-handed carry makes it even more versatile.
