    • A personal (political) note

      Hi,

      I don’t use website for anything except sharpening services. But this week, I’m breaking that rule once, because I think what’s happening in this country is that important.

      On March 28, this Saturday, I’ll be marching in Hudson, NY with the NO KINGS movement, and I hope you’ll find a march near you.

      I’m going because I believe we should:

      • Stop the war with Iran and the bombing of civilians
      • Demand justice for Renee Good and Alex Pretti
      • Protect healthcare and Social Security
      • Honor our veterans — with actions, not just words
      • Make housing affordable
      • Defend every vote — no matter where or for whom it’s cast
      • Protect freedom of speech and your right to privacy
      • Strengthen NATO and defend democracy at home and abroad
      • Stand with Ukraine
      • Hold powerful pedophiles accountable — open the Epstein files
      • Stop the mass deportation of hardworking immigrant families
      • Restore honesty and integrity in government
      • Rebuild America’s standing in the world
      • End the murder of suspects in boats in the open ocean
      • End the disastrous tariffs crushing working families
      • Guarantee universal, free, quality public education
      • Stop exploding the deficit to hand tax breaks to billionaires
      • Protect our public lands and wildlife habitats
      • Take real action on climate change

      If any of this matters to you — stand up for yourself and come stand with us.

    Sharper Service has been sharpening my knives for several years now. Jim does a really great job and I get them back quickly at a fair price. I highly recommend this service!
    Super reliable, professional, and convenient service. Drop off in Ossining on a Tuesday and he will return them within a few days max. Always comes out great.

    Grateful to have my garden tools sharpened like this. It feels like I got my tools back from the dead. I plan to make this a yearly habit after the season is over.

    Jim has transformed my scissors and made cutting veggies in my kitchen possible again. He is knowledgeable and takes care in his work. Just this week he had my knives back to me in one day. Highly recommend Sharper Service.
