Thanks for the review, legodac. Like you said, I'm sure a simple modification to the blade would make it less likely to fall off.

It's not only design that is the problem here, I've found now and then, not very often, a set where the pieces seem to fit a little looser then normal. The bulldozer fit into that not a great fit category.Technically that's unavoidable in certain cases, like for instance some of the old pins on the older Bionicle sets were looser at times(Though I have doubts about it fully being from the set itself, since it's had it's fair amount of usages), but they still worked, though it is annoying when something falls out that's not supposed to at a very inconvenient time.
