There are things for which putty knives are nearly ideal tools, yet
they lack a certain something when being used for really sticky
substances, like roofing tar. I want all the tar to come off the knife
easily!
Putty knives

There exist a wide variety. They are intended to cut putty, and other putty-like substances, so they don't have sharp blades. [Vernon, Nov 07 2016]

Teflon putty knife

This appears to be a Non-Stick Putty Knife - an ordinary putty knife with non-stick coating. [MaxwellBuchanan, Nov 07 2016]

I wonder if a commercial waterproofing spray wouldn't accomplish this. |

// What's roofing tar? // |
|
| |
A revolting, poisonous, sticky goo with a vile odour and worse taste. |
|
| |
Outside the U.S. it's known as "Jack Daniels". |

What's your poison then Mr. Gourmet Zombie? |

As a beverage, single malt whisky. |

Maybe what you need is a Teflon blade. Searching "Teflon putty knife" produces a number of hits, for example <link>. |
|
| |
The answer is simply to develop non-stick putty, shirley ? |
|

[MaxwellBuchanan], did you not notice that the link you provided states that the item is "out of stock or discontinued"? What good is that? |
|

Well, there you go then, [Vernon]. Either the teflon putty knives are available for sale (in which case mfd widely known to exist); or they are unavailable due to the fact that they don't work (in which case mfd - doesn't work). |

Teflon, while amazing, seems a little over-used in the non-stick industry. Surely there are other ways of making things non-stick. How about making the surface of the putty knife like a membrane, with a lots of tiny holes in it, and pumping some fluid out of these holes? You'd have a weird sweaty slippery knife. |
|
| |
There are non-stickier materials than Teflon, but most of them are not very durable, relying as they do on a micro-scale surface structure which is easily damaged. |

| |
Roofing tar is more nutritious and tasty. |

Disposable plastic putty knife. |

Or coat of lithium grease on knife before use? |

[MaxwellBuchanan], regarding your suggested mfd's, I'm
glad I specified "non stick" without specifying "Teflon". |
