Set comes with every blade possibly needed for harvest or sterile transfers. Nearly organized, with more than plenty extra blades.

This is a must need for harvest

Must have for Bulk Grows! I bought an Exacto knife set at the store for $7 but you really need some of these other blades to cut and really are impossible to find at the store. They work so much better than an Exacto knife. I had no idea that I was damaging my bulk grow everytime I picked the mushrooms twisting and pulling. I did notice nothing grew in the spots of the old ones. Thanks for the awesome set for awesome price!

Came fast and arrived with everything in it.

Can't beat the price at $17.99! Great info, thanks again!
