The slipping or breaking of a knife handle while someone’s using it is the worst nightmare! It can cause deadly injuries. Therefore, you must choose only the best epoxy for knife handles.
What kind of adhesive do you like to use for knife handles? I once asked a professional in the industry of knife-making about which glue I should use for such purposes. ‘’Epoxy!’’, he said with absolute confidence! I, myself, have later experienced how good of a material epoxy is. Here, I have shared some of my knowledge of this aspect.
What is epoxy?
Epoxy is an organic compound that is made by chains of carbon molecules connecting to more molecules such as oxygen, nitrogen, etc. It is a kind of polymer and shows exceptional mechanical bonds. This substance is widely used for various types of constructions and also as glue to stick pieces of wood, metal, etc.
Features:
- Epoxy is a polymer made of carbon chains
- It is made through the reaction between the liquid resin and a hardening agent
- Epoxy is a solid and transparent material
- It is used as the base, adhesive, coating, or paint of craft-pieces, jewelry, floors, and many more

This epoxy is a versatile material that works magic on many types of surfaces, such as metal, ceramic, wood, etc. It efficiently works as the bond between even the hardest to bond wood pieces, which makes it an ideal adhesive for knife handles.
The epoxy comes in a liquid form, with separate bottles of resin and hardener. This epoxy gives you around 46 minutes of working time and it takes a few hours to cure fully. Thus, making knives with G/flex epoxy of this kind is easier, because you’ll get much time to work properly and get a neat finishing.

Another wonderful thing about this epoxy is that it is suitable for use between dissimilar materials. Since the handles and blades of the knives are usually made of distinct materials, it gets difficult to make a bond between them. But with this epoxy, that is no trouble! It also works fine on damp surfaces.
Its water resistance takes it up another notch. Even when your knife handle regularly comes in contact with water, this epoxy will not become damp.
Using this epoxy is also trouble-free. You just need to mix the resin and hardener in a one-to-one ratio and it will be ready to use. It is better to leave it overnight or at least 6 to 7 hours for it to completely get cured.
