Knife - Essential Tool for Camping, Outdoor Adventure and collection

T4000 S Ranger Limited Edition is a limited series version of only 100 pieces based on the T4000 model, a reworking of the Japanese Wakizashi short sword that the Samurai carried at all times in contact with the body.

It is a timeless tactical tool that follows no fashion but faithfully adheres to the Extrema Ratio philosophy aimed at fulfilling all functional requirements.

This model continues Extrema Ratio's purest Tanto series designed especially for lovers of the Japanese blade profile, who do not want to give up typical tactical accessories such as textile sheath and special polymer handle.

The blade, made of Böhler N690 steel hardened to 58 HRC and burnished to MIL - C- 13924, features Geotech Camo customization, Extrema Ratio's innovative and original camouflage pattern made by laser engraving.

The grip, in HCS coloring, is made of Forprene, an elastomer that is part of the "NATO standard" due to its exceptional resistance to extreme conditions.

The black-colored Cordura sheath is and equipped with MOLLE system that allows its carrying on tactical vests and general belts and guarantees the safe carrying of the razor-sharp blade by protecting it from shocks that could reduce its efficiency.

The T4000 S Ranger Limited Edition comes in an IP67-certified watertight Polypropylene technical case with pressurization valve that is weather, dust and shock resistant. Also inside is a double-grit sharpening plate (ceramic abrasive and synthetic diamond) and a metal plaque with the numbering of the limited series of 100.

FROM COLD STEEL WEBSITE

The Oyabun Limited is a high-end collector's version of our Oyabun. It shares features in common with the standard model in terms of functionality and appearance, but differs greatly in the materials used in its construction. It also has the value of being a collectible keepsake as only 3500 were produced. Each one is serially numbered and each box will be personally signed by Lynn C. Thompson himself! The blade's fine S35VN steel is an expensive powder coated steel that is heat treated to Rc 59-60 and hardened to sub zero. It has been given an attractive two-tone finish on the blade planes and a high satin polish on the blade bevels. Notably, the handle frame is milled from two solid billets of 6061 aluminum to create the bolster and pommel, which has been given a beautiful mirror polished finish. The handle also features CNC-machined G-10 plates with a diamond checkerboard pattern for a good, secure grip.

"I like flashy knives and when they are limited collector's editions with serial numbers made from high quality materials, I like them even more. That's why I think you'll like our Oyabun Limited. Only 3500 pieces will be made. All individually serial numbered with 6061 aluminum frames, CNC machined handles that are completely checkered just like my much original and a two-tone polished S35VN blade! And best of all, all this splendor and high performance is backed by our state-of-the-art leaf spring lock and secondary safety, so you know it won't bend on your hand. Now you have a knife that is worth every penny asked (just compare) and has tremendous appeal/appreciation from collectors!!!" - Lynn Thompson
