Hello John Barton.
I have not worked tagua nuts but have seen the finished article and
Having used diamond blades for many years I do doubt they are a good
option for sawing these nuts… Diamond blades are constructed for
cutting hard materials that do not give in the path of the cutting
edge, this is why they do not cut your hand, wood or other similar
You could try it John, you may prove me wrong but I believe the tools
usually used for slicing range from bandsaws down though coping and
hack saws. I am confident that you will need to slice with a toothed
saw of some description that cuts a clearance and takes the kerf out
with each cut.
Good luck John, I would love to get my hands on some of those nuts.
