What you need is:
1. A handle from knife or a knife without handle
2. Clear Resin and it's catalyst
3. Small disposable cup for mixing resin
4. A stick for stirring (whatever you can find)
For without a handle, you can make a handle yourself with silicon mold. But in here I will show you how to sealed a handle with resin.
Step 1: Mixing Resin
Step 2: Pouring Per Layer
Step 3: Put Another Layer and Layer
When it's in curing process, the resin is dripping and when it's hard enough, it's make it's bottom surface wavy. When the whole surface is full of wet resin, I put it like in the photo (horizontally). I'm trying to make it not touching anything. If I put it vertically in first layer, it make it worse. The hole that I fill will dripping and make another wavy surface. So... Whatever.. I pour another layer. But it's still make a wavy surface. So I cut a dripping parts that hardened, and pour another layer...
