I recently acquired an Imperia La Roccia 12k-15k I believe it's their premium. Now I have only used this stone 2x once with slurry which seems to cause microchips and once without. The without slurry I have not test shaved as of yet so I can not yet share my thoughts.
My progression was as follows, 1k,2k,5k,8k kuromaku then ILR. I did not count strokes but it was alot compared to my 12k naniwa. Looking under my pocket scope reveals a less than polished edge and misc. Stria not straight uniform stria I am used to seeing.
On a FB page it was suggested to use the hone under running faucet and light strokes. Just curious of any thoughts on here. I know from research these homes are not highly thought of but price was cheap, used. Thanks in advance.
