[ectofix]

Berkel has been manufacturing slicers since 1898.

 

Call 800-814-2028 and ask them.

Across the 800 and 900 series the stones are the same, the older large slicers like the 170, 180 and the 910 have different stones and the newer x13 has the Hobart style stone. The smaller slicers 827 and 829 have their own set of stones as well

so the answer to your question is no, they are not all the same
