Thread: Stupid question

Hi guys I have a real stupid question for you all-
Is a flattening stone what you use for lapping stones?
Thanks in advance
Tony

It is what you are told to use and can use! Most here use a DMT 325 as it is more reliably flat! Sometimes you have to lap your flattening stone!

OK so a dmt 325 is best then?

What about a naniwa 220 grit lapping plate?

Whatever gets the job done - a bit of 600 grit wet/dry sandpaper on a flat surface is also a popular lapping tool. There's no "best" really, just whatever works at your budget. I think most guys like the DMT because it is relatively inexpensive and it is convenient to have a single plate rather than buying sheets of sandpaper all the time. But there are many other options out there.

Thanks James!

Remember your newly lapped stone will have o surface as rough as the lapping stone used.
If you have a stone of equal grit as the newly lapped you can rub them together, use a piece of tomonagura
or just expect it to be a little coarser in the beginning!

Most any 325 to 600 grit continuous diamond 1/4" plate, steel not plastic backed, will work. There are specially graded diamond lapping plates that are guaranteed to meet a certain standard of flatness. I use an eze lap brand 600 grit, but only because that is what I had for knife sharpening. Several of the threads in this search dmt atoma discuss the relative merits of those plates.

I have decided to quit giving advice in the honing section, but there is one thing I know to 100% true with no exception. There are no stupid questions.

The naniwa lapping plate left the surface too rough for my taste. Now I use a 325 DMT.
