Using the Diamond Edge Pro Electric Knife Sharpener

Question via Ask the Expert:

I have the Smith’s Diamond Edge Pro electric knife sharpener. I am wondering what the angle of edge it puts on knifes. I own some shun cutlery, am I able to use them with the sharpener?

Please let me know as I do not want to ruin these knifes.

Thanks,

Jamie

Edge Expert Response:

Hi Jamie,

Thanks for contacting us! The interlocking diamond wheels on the Diamond Edge Pro® (item # 50023) are set at 35⁰ degrees (17.5⁰ degrees per side).  This is very close to the angles used by Shun Knives (16⁰ degrees per side; 32⁰ combined), so it would be acceptable to use the Diamond Edge Pro® to sharpen these knives and not ruin them.

However, please be sure not to do too many strokes through interlocking diamond wheels because it does remove metal quickly.  I would suggest 5 pulls for a normal used knife that needs re-sharpening and 6 – 10 pulls through the diamond wheels for an extremely dull knife that is badly in need of sharpening.  Always finish/polish the edge with 5 or 6 pulls through the manual ceramic finishing (fine) slot.  In addition, please DO NOT to use the manual carbide (coarse) sharpening slot under any circumstances with his Shun knives.  These abrasives could damage your cutting edge.

Let us know if you have any additional questions!
