Modified bk2 and others

the fact that you have a personal plasma table is pretty impressive.
yea that robot is INSANE. it moves at 80 mph and produces 2 G's of force and has 8800 recordable spots in the motors. It is accurate enough to hit the SAME exact spot to within 1mm from 80mph. btw...each motor cost 1500 to replace(as me how i know...lol) what happens when you crash it into a jig

Here is a knife I just finished tonight
I didn't make the knife but I did grind and polish the blade by hand. Took about 4 hours with sand paper and a 1\2" steel plate. Then a sanding block finished with 1500 gritt.
The blade is a a part that came off of a school bus hood latch. It is some kind of pretty hard tempered carbon steel. Reminds me of 1095
It has a small saber convex grindo

This is my homade mouse pad strop. I started at 140 grit then went to 400, 600, 1000, 1500, 4m, 1.5m, and finally .01m cbn emulsion

This was actually not my first intention. Somehow the angles got terribly screwed up on the kme. I was trying to get it to a 15dps edge (knife placement is key and that blade shape and grind make it difficult to get just right) so I was almost ready to throw in the towel and get a new blade for it but ZT could not guarantee the blade would have the same etching on it so I just took the plunge and said..well, what I got to loose
 
Great work!!!

How do you get the line between the polish and black parts of the BK 2 to be so sharp?
 
Very strick on holding my hands on the blade and holding the right angle. Plus I also used a sanding block with parallel sanding motions with a finished 1500 grit wet sand.

I have found that if your are wanting to polish a blade, the parallel sanding motions do wonders for the shine

Oh btw. I forgot to mention I used a 1/2" steel plate and wrapped the sandpaper around it. You need to use a very rigid backing for this.

Thanks.
I also think being a welder/fabricator helps with this as well from having the muscle memory from holding the stinger still for long periods of time. That, and me and metal are friends. :-)

Thanks for explaining. What was your grit progression, start to finish?
 
On the bk2 I first used stripper to get the black off (one less layer to sand) then went from 80, 150, 320, 400, 600, 1000, and 1500. The 4-1500 where done wet sand. I wouldn't worry about using wet sand on the 80-320 (I don't think they make wet sand in those grits do they?)

The ZT was dmt 140, 300. I was going to do the 600 and 1500 dmt but decided to go the convex route because of how jacked up the edge angles were. so I started at 400 wet sand to 600, 1000, 1500, 4m, 1.5m, .5, and .01 cbn emulsion
