The one you show in the picture looks the exact same one I got, with the exact same packaging (I still have my original packaging.)
Mine broke after only a minimal amount of use, but I may have gotten a lemon.
I posted of it broken earlier in this thread, but post it here again because there is so many posts to read through in this thread.
In this thread I posted how I fixed it.
Earlier, in the same thread danchappell had an idea for an easier fix than I did.
Just want to point out that the tool with the packaging which simply says “Grafting Tool” and “Save Labor” on the front is the same one I got which broke quickly on fairly small wood.
Still I wouldn’t worry too much if it breaks because danchappell’s repair method is easy and seems like it be an effective repair method to me.
That said, if there is an alternate choice of one of these knock-offs, one which doesn’t have the aforementioned packaging, you might try that one instead?
