The standard form I've seen (as in "seen *repeatedly*") is securiform.

Most often I've seen this used to describe the terminal segment of 
antennae or palpi. Any coleopterist should be familiar with it.

The only other term I know, which I've only seen used in species 
epithets, is "dolabratus", which would Anglicize as "dolabrate".

Peace,
