yes guys, please be very carefull when working with a x acto knive. After being in the hobby for five years I two became careless and slipped into my hand stabbing 3/4 of the blade into my hand. I ended up in the Emergency room. I am really glad I pierced my palm then one inch lower in my wrist. I always though keeping my had a good distance away from the blade would be save. I was working with my left hand on holding the tail of the plane on the top. I was cutting out splintered wood on the bottom of the fuse when the knife slipped out and I forcefully threw the blade rearward.
