Query: Be Very Careful with the French Fry attachment!!!

I was initially very happy with this product when I used it to slice vegetables for salads. The other night I decided to use it for slicing french fries. I inserted the blade with no problem whatsoever and sliced my french fries (very sharp blades). When I tried to remove this blade, it would not come off. I finally did get the blade off but in the process managed to slice my thumb deep enough that a visit to the emergency room (and 4 stitches!) were required to put everything together. I have tried (unsuccesfully) to contact HOFFRITZ customer service to let them know of my mishap but apparently their e-mail address does not work.Hope you don't go through the same ordeal when you use this attachment.
