Another good tip is filling a bucket with sand and oil.
When you’re done with shovelling just put the shovel in the bucket and it wont rust.
Same with carbon knives, if you’re not gonna use them for a few weeks,give them a thin layer of oil to protect them.
Use food grade oil as you’re cuttting vegetables or other food with them.
As Malgus says, heat is not good and a steady hand with a slow sideways motion will help.
Choose the right angle for the chore and you quickly will get the hang of it.
