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 https://www.lowes.c...ls-Paint/4294515325
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]

       What's roofing tar?
MaxwellBuchanan, Nov 06 2016
  

       Call that a knife?

       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".

       As a beverage, single malt whisky.   

       Otherwise, Zyklon-B ...

       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?
Vernon, Nov 07 2016
  

       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).
MaxwellBuchanan, Nov 07 2016
  

       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.

       'I can't believe its not putty', high in polyunstickulates.

       You're not saying it, but I think you're talking about marmite.

       Roofing tar is more nutritious and tasty.

       Disposable plastic putty knife.   

       Or coat of lithium grease on knife before use?
bungston, Nov 08 2016
  

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