How do you chisel curves?

[Shotgun]

I want to make a handle for my Izula 2 using the method in the vid below. Basically cutting out the outline of the handle so that two pieces of wood sandwich together to provide a hidden tang handle. It seems pretty straight forward but I'm not sure how to do the curve on the butt. I've never used a chisel before so I'm not sure if a curve like that is doable with one.



Edit: Pic of knife for reference.

When I tried this I used a utility knife to cut into the wood along the shape you want. Then chisel the wood out and by having cut into the wood already it should come out nicely.

Okay. Thanks.
