My first point

(1/6) > >>

Well here it is, just like the title says, its my first point.  At least one that I didn't break.
I got the rock from Scott at mojam this year.  Im sorry but I have no idea what its called. 
I know that its not perfect, but im kinda proud of it. 
I would appreciate some critique because im trying to learn.  I do have a question though. 
I have a ton of plate milk glass.  It seems to knapp really well.  But the problem I have is that it pretty much all has 90 degree edges.  How do I go about angleing the edges so I can get the edge sharpened?
I have broken most of them except one.  (second pic)

Second point,  I put it on my trade arrow.

Good job Patrick. That first one looks pretty good. The second one looks like naviculite which to me is harder to get a nice scar pattern with.
For working glass and 90 degree angles. First lightly abrad flat 90 degree edge. Then I do what you call scissorsing the edge. I usually start in a corner. The abrading will help get a grip on the slippery glass and also get rid of lose weak material. Try to get a shorter flake off in corner, then flip piece over. Using the angled edge of your first flake try to make a second flake on opposite side of piece.Dont use middle of removed flake edge. Use side of it and lightly abrad it. Flip over and continue process. You should develop a zigzag edge. Once your all the way around you basically have a biface. I'm not sure how plate glass works, it might be a bit thin. I find anything I can practice with especially if it's free, has helped me tremendously.
Looking forward to seeing more

Thanks Bj,  I tried that this morning and it seems to work better.  I watched a video last night where a guy was showing how ishi was making his last point before he died.  It was a piece of plate glass worked in the way you discribed. 
The glass I have is called milk glass,  it was in 4 foot sheets and was used for shelving in my grandma's feamarket.

lebhuntfish, nice first point, I like. On your milk glass( sg edge) materials stitch your edge with short flakes , move edge to one side and next pass longer flakes to start building convexity, flakes don't want to travel far on a flat surface. Bob

mullet:
Nothing wrong with those, Patrick. That first point is Georgetown. You did good.
