I'm pretty sure all prop pullers pull from the hub just because of damage like yours.
Here is the type I used...
There are other designs if you don't have a lot of clearance between the prop and the strut hub.
You'll probably have to tap the forward side with a hammer. Try a rubber hammer first. And just loosen the inboard nut a couple turns. Do NOT remove the nut as pictured above.When the prop gives, it gives all at once and will pop off the shaft if you let it, tool and prop now on the ground, feet, etc.
