Hello Jeanne, product dimensions are 0.25 x 1.88 x 5.88 inches
Yes these fit every Utility Knife I own from Stanley to Harbor Freight and all in between, Hope this helps !!
Yes this blade will cut you badly !!
Yes
11-921K indicates that it is a 100 pack of the current blade. 11-921L indicates that it is 50 of the current blades. 11-921A is a 100 pack of the blades but in a classic 1992 style.
Not unless you want stiches
The dimensions of the 11-921K are listed as 7.50 X 2.5 X 1.2. Please contact STANLEY at 1-800-262-2161 for further assistance.
I would say yes most all are standard now. Sometimes maybe a problem with heavy duty blades being to thick for regular knife to operate smoothly.
Unfortunately it does not.
yes
