Current chatter has it the Texas mass knifing was done using an X-acto® knife or, as they must be hoping, some cheap knock-off. (For all lawful purposes, stick to the real thing; they really are better made.) Given that these little knives have no "sporting purpose," are slightly similar to some kinds of knives used by professional surgeons and that readily replaceable blades are sold in handy "magazines" or "clips" of 50 or more, should we be looking out for a push to ban "assault knives?"
Great. Bare shelves at the art-supply stores. You already can't hardly find them at the drafting-supplies stockist.*
...Meanwhile, in Serbia, a country with approximately the same gun laws as New Jersey, there was a mass shooting -- yes, there are guns a-plenty left over from the Late Unpleasantness, but the one used in this was owned in accordance with all the registration, licensing and safe-storage laws they've got. Background checks, testimonials, head-candler's report, ammunition-quantity limits, they've got 'em. And the nutjob kept going until other men-wth-guns arrived to oppose him.
One might almost suppose there was a moral here.
* Now there's a trade that went digital early, rapidly and often.
