Repair kit?

I wonder if instead of the current repair system we can have crafter make (one use) repair kits (that will stack). Like leatherworker can make peiste cesti repair kits which a pugilist can buy and use in the field to bring the peiste cesti back to 100% condition.

This way crafter can have something that will always be in demand to sell and gatherer/fighter will no longer have to return to town to repair their gear.

I know it won't be very realistic, but i really do hate it when my cesti drop down to 0% while i'm in coerthas... Also this way my carpenter can have more items to sell.

what does everyone think?
