Frequently Asked Questions
Everything you need to know about our professional sharpening tools and services.
How do I know which grit size I need for my knives?
Grit choice depends on the blade's condition. Use a coarse grit (200-600) for repairing chips, a medium grit (800-1000) for general sharpening, and a fine grit (3000-8000) for polishing and achieving a razor-sharp edge.
What is the difference between a water stone and an oil stone?
Water stones use water as a lubricant and generally cut faster, but wear down more quickly. Oil stones use honing oil, are much harder, and stay flat longer, making them ideal for tools that require precision flatness.
How long does shipping take for domestic orders?
Most orders are processed within 24 hours. Standard shipping typically takes 3-5 business days, while expedited options are available at checkout if you need your supplies sooner.
What is your return policy for sharpening stones?
We offer a 30-day return policy on all unused items in their original packaging. Please note that used sharpening stones cannot be returned due to the porous nature of the material and surface wear.
Do you offer international shipping?
Yes, we ship our sharpening supplies worldwide. Shipping costs and delivery times vary by country and are calculated automatically during the checkout process.
Are your products covered by a warranty?
All professional-grade sharpening equipment sold through Sharpening Supplies carries a minimum one-year manufacturer warranty against defects in materials and workmanship.
