01 / Know your steel
A good edge begins
with understanding.
Different steels ask for different approaches. Steel Sage helps you find the right one for the knife in your hand.
Let the Steel Wizard narrow it down.
Four questions about how you use a knife. A ranked shortlist that leads straight to a sharpening recipe.
From steel to stone.
Get a grit progression and target angle for your steel and setup. Start your session with a plan already in place.
Live Angle Coach
A steadier hand.
For freehand and strop, your phone's motion sensors read the bevel angle in degrees per side. Haptic and voice feedback help you stay on target.
Your sharpening setup
Work with your tools.
Use stones and strops, or guided systems like Wicked Edge, KME, Lansky, and Work Sharp. Guided systems get setup calculations for their geometry.
My Knives & Log
Remember what works.
Keep your knives, recipes, and sharpening sessions together. Follow each knife's history and see how its edge holds up over time.
Steel Leaderboard
Learn from the field.
Anonymous reports add real sharpening experience to the picture. A steel is ranked after five users have reported.
