What is the texture supposed to be?
A knife, the handle wrapped in a black cloth and the blade looking a little, distorted.
The texture is very off of what it should be.
This is what hunting knives usually look like:
Notice that there is no swirling / blending-like colours as you made. Instead, there may be 3 solid-filled colours on the knife. The handle, completely black. The guard, mostly silver with a black stripe (but you can just fill it a solid dark-silver / silver colour). Then the blade, completely silver.
Overall, there is no need for that swirling texture. Just a solid filled texture of each area will suffice.
It’s not supposed to be a hunting knife at all.
The knife model you have is a hunting knife, but regardless what I said still applies.
I’ll be honest, the texture looks like liquid metal or foil.
