Hinderer XM-18 - the famous knife from Rick Hinderer

Knife XM-18 with a 3.5-inch Spanto blade and a flipper — fresh, of the last 4th generation. XM is an abbreviation that stands for eXperimental Model, i.e. “Experimental model”. 18 – the number of the unit in which Hinderer served as a firefighter.

For model XM-18 3.5? Four generations are distinguished; they differ in design features and details: the design of the handle, the location and number of markings, the shape and size of the pegs, etc. For example, one of the main differences of the 4th generation from the 3rd is the location of the stop pin. In the 3rd generation knives, the blade in the closed position rested against the stop pin in the area of ​​the choyle, and the stop pin itself was located in the middle of the handle. In the 4th generation, the stop pin has been transferred to the “back” of the handle, and the blade rests against it in the heel area. This potentially allows you to completely get rid of the coyle and create new forms of blades.

For the first two generations, the blades were made manually, for the 3rd and 4th – on CNC machines or manually. So, probably, the 2nd generation knives are the most desirable for collectors, but the new ones are the most affordable – the 4th. In various generations, steel was used for the manufacture of blades: Crucible CPM S30V, Duratech 20CV, Carpenter CTS-XHP, Crucible CPM S35VN, Carpenter CTS-40CP.

Another important detail that is Hinderer’s proprietary development is the frame stabilizer LBS. This element in the design of folding knives appeared after Rick in a critical situation (acting under stress and in thick gloves) bent the frame-lok, bending the plate too hard. This made his knife useless, because the lock simply stopped locking the blade. LBS serves as a stop, which does not allow to bend the lock plate more than necessary to close the knife. In addition, LBS stabilizes the frame-plate plate and does not allow it to slide along the heel of the blade if you squeeze the knife handle with effort. This should prevent premature wear of the lock and remove play in the lock, which can potentially reduce the reliability of the knife under load.

It should be noted that the demand for Hinderer knives remains quite high, for this reason the prices at dealers and in the secondary market usually exceed the official ones, which are widely published on the manufacturer’s website. The nuance is that directly, at their prices, Hinderer sells knives only to current law enforcement officers, military, rescue workers and firefighters. All others must seek happiness from dealers or in the secondary market.

If for custom knives, the blades of which are made by hand, there are different alternative forms (for example, Bowie), then the serial models are made with three versions of the blades: Spanto, Slicer and Wharncliffe (or Wharnie). Usually the blade has a flipper, in the open position the flipper becomes an additional stop (and protection) for the index finger. There are models without a flipper, only with pegs. Below you can see photos of various profiles of blades taken from the manufacturer’s website and at the company’s forum. Note: on the blades made by hand, the descents on the main part of the blade are concave, and on the serial blades the descents are straight.

The Slicer profile shifts the balance of the blade from Spanto’s excessive strength towards a more comfortable cut. The descents are flat, the descent line gradually rises from the middle of the edge of the blade to the butt. With all this, the tip of the blade can not be called too thin or tender. The blade with a pronounced cheyl, along with a notch on the butt, allows you to intercept the knife for more accurate work. The handle has a deep subdermal groove, the flipper forms an additional support for the index finger. The notch on different parts of the handle allows you to securely hold the knife straight and reverse grip. The texture on the textolite pad also contributes to the comfortable retention of the knife. The texture is tenacious, but still not fine sandpaper, which means it will be more gentle to the pockets. Processing blade, titanium lining and clips – Stonewash (tumbling). This is a visually beautiful and practical treatment option, which is not so noticeable marks with the active use of the knife.

The knife is assembled on 4 screws: a large axial screw with a straight slot and 3 screws of the Torx T8 handle. The counterpart of the axial screw is non-standard and, if it is necessary to press it when tightening, you may need a special tool. All screws, stabilizer LBS and bonki made of stainless steel. The bronze color in the axial screw slot is the result of quenching. The screws that fasten the clip have a cross-shaped slot. The clip on this knife is installed in the Tip Down position, the second recess in the handle, for moving the clip to the Tip Up position, is closed with a special plug. Fluoroplastic washers, smaller from the side of the frame, and large from the side of the lining G10. Under the pad G10 is a titanium liner.

You can replace standard steel screws, screws, an overlay from G10 and even a clip with a cap, which allows you to significantly update the look of the knife and personalize it. For example, from a manufacturer or dealer, you can buy accessories made of titanium, anodized in different colors, bronze or brass. Covers are available in different colors, with different textures or a smooth surface, from G10, carbon or titanium. Steel Flame offers clips, caps and other details with silver jewelry. All of these elements are usually easy to change, thanks to high precision manufacturing.
