LOL,as soon as I read the topic I knew what I was going to write, I see those who say you will get cut and I figure I am in and then I read Nick's post and see his view is the same as mine,shot out of the water,lol.
I agree with Nick,you may POSSIBLY get cut.
Unless you watch it cut into you ,you will not realize you were cut until it is over.(you will feel like you were punched) watching it cut may cause a higher adrenaline rush or shock,but it depends on the mindset going in.
If you fear the cut or if you do not care about what happens as long as you win.
If you decide to engage then do it,period,no half stepping either go at it and end it or give up,as Nick says,if you are mentally saying "I will get cut" this will cause hesitation of action and result in most likely telegraphing your intent ,when you get the nerve ,to go forward.
I have been in 6 knife altercations:
I got stabbed at from behind while choking one guy out from the rear and his friend tried to stab me,but I turned and the stab turned into a slash of my arm.
Felt like a punch till I turned and saw he had a blade,no blood till later.
A second time ,(I had been taught to grab the blade and I did) ,a single edge blade sharp edge up and the attacker pulled back and I almost lost my thumb.
Blade cut through the meat under my palm,through the webbing around to the top.right around the joint,about 340 of the 360 degree possibility.
I saw it happen and realized what happened but did not feel the pain till later, there was not much blood during or after the cut and I was able to use the hand,(not to try and grab any more lol),but closed fist and open hand strikes were fine.
(who ever came up with grab the blade must be grabbing butter knives,lol)
I had a guy try to rob me with a static blade and never got cut.
3 other times I was able to use improvise weapons on the street,(trash cans twice and a burned chistmas tree once)
If you must act,ACT,do not hesitate and do not think of the possibilities prior to the act,just do it or not,your choice to be made in a nano second.
(Also never grab a blade,lol)
