scavenge item question

[snoop1050]

just hit lvl 10 ranger a few hours ago and was playing with this ability and found some rusty quiver case (with item desc something like "this rusty box still contains some bolt's"
so im wondering if these are useless or if theres some synthesis ie light crystal (restore/repair) + rusty case = #?? bolt's or bolt quiver full off #?? bolt's

Use the case.. you will obtain some rusty arrows.. they suck.. and are like neg3 acc.. good for farming since they are totally free.
