Spall to biface to what next

[GooseGossett]

So I've got to this point a couple of times and then I tend to end up with a oval with notches.  I'm wanting more triangle or ishi style.  I'm talented at crunching my way and tips breaking off making them shorter and stockier.  Y'all have any tips to keeping the tip intact while scrunching and getting the profile down?

You might want to take a pencil and draw the point your looking to make.Leave the tip alone it looks good ,after you bring the sides in more you can touch it up with pressure.Set up some platforms on the sides and bring them in ,the base can be worked a few different ways depending on what kind of notches you want. You'll get it ,takes time and rock

That's a pretty peice of rock - go easy . I'll usually roughly abrade the shape i want at that point. Abrade down, flake, flake, flake, turn over repeat kinda fine tuning as i get closer. Never have used one of those edge crunching tools, just my abrader.

I did try spalling/crunching once or twice but found much better results with abrasion after each round of flakes until I got the shapes I wanted.
