The Harbinger signals the arrival of violence, a forewarning to those who stand before it.


/ˈhɑːbɪn(d)ʒə/ - a person or a thing that signals the arrival of something else, a forewarning.

The Harbinger was designed to be in line with a more traditional fighter profile, resulting in an asymmetric dagger that feels as good in a reverse grip as it does in the forward orientation.

The edge geometry of the Harbinger heralds the arrival of the Hybrid geometry seen now on many of my double edge models. In this case, the reverse edge is flat ground, with the conventional edge ground as a convex edge. The result being a very sharp edge for reverse grip pikal techniques, and a more robust forward edge for slashing. The hybrid geometry also reinforces the point slightly.

The blade itself is offered in either Elmax or Hitachi’s Yasugi series Blue Paper #2 steel. Both of these high performing steels offer different characteristics. The Elmax blade is extremely tough and robust, while also having the added benefit of being stainless and somewhat easier to maintain. The Hitachi Blue Paper #2 is a high tech powder metallurgy high carbon steel, with one of the highest carbon content’s available in a mill steel it produces extremely sharp edges with a very fine carbide structure. Both choices are a good one, with the Elmax leaning more towards robustness and less maintenance, while the Yasugi steel is closer to a traditional Japanese high carbon steel and produces an exquisite edge.

While the Harbinger is on the longer side, it is a slender and well balanced blade that feels agile in the hand, with a very natural ergonomic handle. Handle options include both the use of Exotic hardwoods and Burls to create luxurious grips, or the full traditional Japanese Tsukamaki handle treatments Ironside Edge Works is known for. The full Tsukamaki features both the front and rear fittings, or “Fuchi” and “Kashira” pieces to create a seamless clean handle. Both options are suitable choices and finished to masterworks levels to make the Harbinger an heirloom quality knife.

As with all Ironside Edge Works knives, the Harbinger is supplied with a bespoke hand made Kydex sheath, pressed specifically to fit your knife, ensuring perfect fit, retention and comfort. Either a full or fold over sheath can be supplied with a Discreet Carry Concepts HLR clip. Alternatively, a Pocket Hook style sheath or Static Line sheath can also be made for it.

Lastly, and to complete your Harbinger, we meticulously hone the edge on Japanese Water Stones to produce a mirror polished edge that cut with ease.
