Most tools use are your "garden variety" (pun intended!) tools of cutters and scissors. The lifespan depends on how well you clean and take care of them. I would estimate for a 2 man harvesting job you would be spending a maximum of ,- on tools. Free tip, if you're harvesting for a longer period or more frequently, investing in a decent chair is very welcome! Trimming buds to perfection is a pain in the ass enough!
