/diy/ - Do It Yourself

I want to make a copper gardening trowel and dont know the best way to attach the wooden dowel to the copper. TC20 has the best reviews for adhesive based bonding however it is not suggested for outdoor use. Is there another suggestion that would hold up to gardening work? Should I just consider a mechanical join and how would that look / what would I do? I appreciate any suggestions, perhaps a knifebro or gardenbro has some advice for me.

Thanks.
