The knives displayed here are one of a kind, handcrafted pieces. The Sahara and Makiti Folders all have the award winning Bertie Lock bolster tilt mechanism. The blade unlocks when open, by pushing both the bolsters up at the back, the blade unlocks and can be folded closed. This mechanism is unique and was developed by Bertie in 2001

Bertie’s logo is to be found within a Stanhope lens on the knife. This method of marking his knives is unique and also it compliments the beauty of the knife, and it eliminates defacing the damascus blade with an etched or stamped logo.

To view the logo, the lens must be held quite close to the eye and on looking through the lens, his logo appears / is visible.


Stanhope lens: invented by Lord Charles Stanhope, an English scientist (1753-1816). It was ground from one piece of glass with one flat and one domed side. The object to be viewed is placed on the flat side . The convex side is held in front of the eye and magnifies the picture (logo).

Jade Makiti 2


Jade Makiti

This is a rather special Makiti, let's start with the blade, it is a composite Damascus blade, the back portion is Nickel and Carbon steel alternating, I call this pattern Pinstripe, and this is welded to a piece of baby Dragonskin to form the cutting edge. Blade is carved as usual and coloured. 100mm blade, 220mm overall.

The handle is stainless steel with Black Jade inlays on either side, and Julien Marchal has worked his magic, doing a stunning job on the engraving.

Seaspray 2

This is the second knife along this theme, it has 72 gold (24ct) inlays in the handle.

Seaspray 2013



The Seaspray Sahara's both have Pinstripe and baby Dragonskin blades, the handles are coloured stainless with inlays of the finest Lapis Lazuli I have been able to source over the years. Julien Marchal designed and perfectly executed the gold inlays and engraving. These are some of the most special folders I have made.

Dragon lady Sahara1


White Line 


The Dragon Lady - Sahara

This Dragonlady has a stainless damascus blade, stainless bolsters with a dragon's wing inlaid in 24ct gold, and the mammoth ivory scales are carved to resemble feathers. Sole authorship.

The Sahara folder was the first folder to feature the award winning Bertie-lock bolster tilt mechanism. It is essentially a lockback mechanism but to unlock the blade both bolsters are tilted upward at the rear and a pin connecting the bolsters together then lifts the lockbar out of the blade notch and releases the blade. As the balde is closed the bolsters return to their original position. See picture below...
