KB by Kubey El Dorado KB469D is the bronze version of Derek Sharon’s compact folder. The Böhler M390 steel blade is paired with an anodized titanium handle featuring Micro Milling, a Slip Joint mechanism, and a pivot mounted on phosphor bronze washers.
The 75.00 mm blade features a Clip Point profile, a flat grind, and a silver bead-blasted finish. The knife opens manually via a Nail Nick, which allows for comfortable two-handed operation.
Böhler M390 and Vacuum-Cryogenic Hardening
The blade is made of Böhler M390 steel, hardened to 60–62 HRC. Vacuum hardening combined with cryogenic treatment promotes high hardness, wear resistance, and stable steel properties during regular use.
Clip Point, flat grind, and Silver Bead Blasted
The Clip Point profile ensures a precise tip and versatile cutting geometry. The flat grind supports efficient cutting, while the silver bead-blasted finish gives the blade a matte appearance that contrasts well with the brown anodized handle.
Bronze Titanium, Micro Milling, and Slip Joint
The handle is made of titanium, anodized bronze, and features fine Micro Milling. The titanium backspacer and clip have a gray, sandblasted finish, creating a distinct yet subdued contrast with the handle’s surface. The clip can be mounted on the right or left side in a tip-up configuration.
The Slip Joint mechanism holds the blade in place without using a traditional lock. Combined with the two-handed Nail Nick opening system, this configuration may be important in countries where laws restrict the carrying of locked or one-handed opening knives. However, final compliance depends on local regulations.

Frequently Asked Questions
How do I care for Böhler M390 steel?
It’s a good idea to clean the blade regularly and dry it thoroughly. M390 has high corrosion resistance, but proper care helps maintain sharpness and the blade’s appearance for longer.
How do I sharpen the KB El Dorado?
High-performance abrasives, especially diamond ones, work well with M390 steel. It is best to guide the sharpener evenly and maintain the factory edge geometry.
What sharpening angle should be used for the KB El Dorado?
The recommended sharpening angle range is 15°–20°. This allows you to adjust the edge geometry to your preferred balance between cutting aggressiveness and blade durability.
How does the Slip Joint work?
The Slip Joint holds the blade in the open position using a spring-loaded element, but does not lock it in place with a traditional locking mechanism. Therefore, you must maintain control over the blade when closing it.
How to maintain the pivot on phosphor bronze washers?
It’s a good idea to keep the area around the pivot clean and regularly remove dust and fine debris from it. If necessary, you can use a small amount of a cleaner designed for the pivot mechanism.
