Assisted opening knives were a bit of loophole anomaly. Because they operated on the cam action of the main spine spring rather than a separate button operated spring they fell outside the definition of a switchblade, which was already covered by the Offensive Weapons legislation ( inasmuch as a switchblade is an offensive weapon per se). So an assisted opener is just as "dangerous" as a switchblade or flick-knife. You previously needed to have a good reason to have one with you in a public place (because it wasn't a simple folding pocket knife) , but now they are banned from sale or carry under most normal circumstances.So I take it open assist knives with the spring removed are still legal.
I can't imagine how an assisted opener could be modified to stop it springing open without rendering it completely useless as the spine spring would have to be filed or cut, so it wouldn't stay open, let alone lock. Having said that, if you could modify it so that the blade could be thumbed open but didn't open of it's own accord, then if it locks we're back to "good reason to have it with you" . If it simply folds closed and doesn't need a separate action to close it, then as long as the cutting edge doesn't exceed 7.62cm it can be classed as a folding pocket knife.
