Digging “tools” would be more appropriate, if you are trying to cut anything other than dirt you will be sorely disappointed.
DK-1 Steel Digging Knife
The stainless steel used in the DK-1 is selected for toughness. Full tang blade, 8″ long, 1″ wide, and 1/4″ thick. Weight is just under 10 ounces. Anodized aluminum slab handles attached with stainless steel fasteners.
DK-3 Non-Conductive Probe
The non-conductive probe provides more digging ability than a standard round probe, and can be safer to use than a metallic knife when dealing with pressure plates. Not that stabbing IED’s is ever a good idea… These are a consumable item, depending on the soil and use the tip will wear down over time, so there is no lifetime warranty on the non-conductive probe.
