About the Hinderer Knives Tri-Way XM-18 3.5 Flipper, Orange G-10, Spearpoint Stonewashed Blade
The XM-18 is known the world over as one of the toughest tactical folders regardless of your mission. Rick Hinderer’s focus when designing the XM-18 was a no-nonsense tactical tool ready for the simplest cutting tasks to high-speed low drag operations. It’s available in a 3″ model, a 3.5″ model (this model), and the 4″ model is designated the XM-24. The Tri-Way model incorporates a ball bearing pivot for supremely smooth action and also includes a set of regular washers that can be installed if you so choose.
The XM Series 3.5″ model has a blade thickness of 0.165″ and a handle thickness of 0.54″, making it a perfect, hard-use design for EDC. The oversized choil permits choking up on the blade for more precise work. The blade locks up on a solid 1/4″ diameter thumb stud which is press-fitted into the blade. This makes for a very strong lockup as there is no loosening of the thumb stud which can happen with two-piece designs. The fact that the thumb stud locks up against the frame adds an incredible amount of strength to the sideways torque of the blade as the sideways stresses are being stopped by the whole handle side, thus relieving the stress that would normally be put on the pivot.
Speaking of the pivot, Rick Hinderer makes his own 17-4PH Stainless steel pivots on a state-of-the-art CNC turning center, thus guaranteeing precise accuracy. The pivot is a 1/4″ barrel diameter with a 3/8″ head. The pivot is drilled and tapped completely through and is mated with a custom-designed screw. This system makes for an incredibly strong pivot that is easy to adjust in the field.
The XM folder handle shape is designed to be very ergonomic and comfortable in a wide variety of user positions. Not everyone’s hands are the same size, and also grip varies greatly, so the ergonomic handles design is a great fit for all users. The textured pattern used on the handle scale is extremely grippy but does not ‘bite’ the hand during use. The 3D texture is designed to flow liquids (such as sweat, oils, blood, etc.) away from your skin and into the valleys of the texture.
The lockside is precision CNC manufactured from 6AL4V titanium featuring the patented Hinderer Lockbar Stabilizer. The knife can be set up for either tip-up or tip-down carry. The non-lock side has a .05″ titanium liner with a G10 handle scale. These high strength materials combined with the full titanium liner add strength and rigidity. The handle scales can be easily changed by the end-user if another color is desired. The standard finish on all XM folders is a highly durable tumbled/stonewash that will stand up to hard use in all environments. The handle construction is an open back design utilizing huge standoffs. The standoffs are designed to add superior strength for lateral crushing of the handle case while still allowing the blade to nestle into the handle without touching the standoffs. This gives the knife the same strength as a solid back folder while offering the ease of cleaning due to the open design.
