Hey its Robert again, do you spend a lot of time on a speed bag? The speed in your hands is phenomenal! I have spent a lot of time developing a lot of useful techniques of my own- I tend to do surprise grip shifts off my legs not my arms, although I also taught myself some reliable grip shifts i do in my hand cause I commonly have a sap or a 1000 lumen tactical light in my other hand. I carried 2 knives for long time- 1 fixed 1 folding but I noticed 2 large combat oriented knives freaks people out in a lot of places
