We sharpen knives freehand with a three step process, removing only as much metal as necessary to prolong the life of your blades.

  • First we restore the edge with a water-cooled grind stone to protect temper.
  • Next we hone the edge with fine grit.
  • We finish it off by polishing it on a third wheel to achieve the sharpest edge possible.

For scissors, we use a sharpening system that sharpens and hones at custom angles with precision to get your scissors cutting better than they ever have.

What Customers Say

Great job! We plan on using them at Blues City Deli many times in the future.

Great price, great customer service and quality job!

Vince Valenza, President, Blues City Deli
My knives are scary sharp! Nice job, Seth and Maria.
I was most pleased with the service I received from Jansen Sharpening. I sent them all my straight edge Cutco knives to be sharpened. They came back in great shape. Working with sharp knives again makes food preparation much more enjoyable. Thanks again!

I had not had my knives or scissors sharpened since I got married nine years ago. They were very dull! After the Jansens sharpened my knives and scissors, they became much easier to use. I used to dread chopping vegetables – now I enjoy it!
Heather S.
I do a TON of food prep! After Jansen Sharpening took care of my favorite chef’s knife, my prep work became much quicker and much more enjoyable.

The professional sharpening job is lasting a lot longer than what I get from the little knife sharpener I have at home.

Jansen Sharpening offered speedy turnaround and skilled artisan services that renewed our dull, mid-life collection of knives and scissors. We highly recommend them!
