They feel sturdy enough in hand to perform bottle opening and simple screwdriving needs and maybe even some light prying tasks. The clips fit securely on my cap, so I didn't feel any worry about it slipping off on its own.
I'll have to see if I can add any knot work to them without affecting the fit while attached to a hat/cap. I think they'd make a nice simple gift for hat wearing friend/family members. At the time I bought the combo set, the price was less than $9 shipped, so I like 'em.
