Subjecting your knife to cold temperatures only makes the joint more brittle. This type of failure is common when a knife is dropped, not unusual during shipment. DDK repairs epoxy joints by carefully scraping away any remaining epoxy residue and cleaning the two surfaces thoroughly. Our own formulation of epoxy is then applied to both surfaces. The surfaces are joined with a sliding motion carefully eliminating any bubbles or voids and checking the angular alignment of the two parts.
Excess epoxy is removed with a bit of sandpaper and then resharpening of the edge is carried out.
There is no extra charge for an epoxy repair. Several laboratory microtome knife sharpening instruments with adapters to handle tungsten carbide knives have been available for some time. Operating these instruments involves having the necessary accessories, disposable supplies and training in their proper use. Only recently has the confusion surrounding the details of their proper use subsided making it possible to resharpen your own tungsten carbide knives. This is especially important if you have been using a laboratory sharpener or a less expert resharpening service.
