There are 2 types of shafts/blades... standard and tapered. Standard shafts require standard blades, and tapered shafts require tapered blades. The tenon on the tapered blade is thinner than the standard one. I think ABS blades are typically standard dimension. Check what your shaft is and buy the appropriate blade.
Here's a quote from the Hockey Giant website:
"The opening at the end of a hockey shaft into which a blade is inserted is called a hosel. There are essentially 2 different hosel types: Standard .620" & Tapered .520" – they are not interchangeable. Standard .620 (non-tapered) blades will only fit into Standard .620 (non-tapered) shafts, and Tapered .520" blades will only fit into Tapered .520" shafts.
In addition, blades are manufactured in Senior, Intermediate and Junior sizes. Junior blades will only fit into junior shafts; senior blades are most often manufactured to fit in both senior and intermediate shafts. Most manufacturers do not make intermediate blades, though most will offer an intermediate shaft."
