Installing the New Knife Handle Using Hot Glue Melt

You can use epoxy to attach the new handle, but it will be challenging to remove if you need to make any changes. Hot glue melt is a better alternative because it is easy to apply and remove when necessary.

Step 1:

The new knife handle you ordered from boogwa will be made to fit the tang of your knife. However, you need to test fit the handle onto the knife to ensure that it fits perfectly in the desired position.

If the hole is too tight, use a wooden file to expand it until it fits snugly onto the tang.


Step 2

Take the knife out new handle, cut small pieces of hot glue melt and stuff them into the hole in the handle.

Or if you have a hot glue gun, you could make long, small piece of glue. Then put them into the hole. If you have time, this way is better

Wrap the part of blade tang and handle of the knife as shown to avoid getting glue on them during assembly. If they get dirty, don't worry because it's very easy to clean.

You could grab the blade as well to avoid any accident when installing

Heat the knife handle and insert the blade into the handle. The heat from the knife handle will melt the glue, filling the handle hole. The glue will be soft for about a minute, during which time you can adjust the knife to the perfect position. After that, the glue will dry and the blade will be firmly attached to the handle.

The glue will harden when it dries, so you need to heat it up to remove it or tap it out as in step 1. Place the knife in an oven at a temperature of 70-80 degrees Celsius for about 4-5 minutes. Bake longer if the glue has not melted and has not been removed by tapping it out. Or boil the knife handle in boiling water for 2-3 minutes until the glue softens and can be removed. To avoid damage for the handle, please remember to wrap it before putting into the water.
