There is something pretty wild on the way from Boker, targeting a Spring 2026 release. This is the Extension Knife, a kukri-inspired fixed blade with a blade that can be used at two very different lengths thanks to a pivoting handle system.
Even if it didn’t have the headlining extendable blade feature, the Extension Knife would be an impressive piece of cutlery. In its full extended position, the blade measures 7.3 inches long, and when “retracted” it’s still a pretty imposing 4.7 inches. While it certainly has a “tactical” vibe, Boker’s copy points out that the intended category for the Extension Blade is actually the outdoors knife segment. Made from D2, this blade should manhandle most chores in that field without a ton of fuss.
But let’s talk about the central feature on the Extension Knife: its rotating handle construction. When the handle is rotated “out,” that exposes the full 7.3-inch cutting edge, complete with its aforementioned kukri-esque recurve. Unlocking the cross bolt and rotating the handle around results in the 4.7-inch configuration, which is not only shorter, but actually a different blade shape, because the narrower stretch of edge behind the big belly is covered up.
Turning the handle over reveals the secondary security feature, a hand-turnable bolt that can be screwed down to keep everything double-tight. Although the symmetrical, barrel-girdle handle might evoke classic U.S. military pieces, it was evidently inspired by the baselard, a medieval short sword with a handle very much like this one. No one is expecting the Extension Knife to be light, and it weighs in at 15.6 oz. A Kydex sheath is included, to be used in conjunction with its shorter configuration.
The Extension Knife won’t be hitting shelves till next April, according to Boker.
