Wiha Universal Edged Razor Scraper

      Comments Off on Wiha Universal Edged Razor Scraper

Today we have the Wiha Universal Razor Edged Scraper.  This is a tool used to remove residual glue, film and labels on hard surfaces.   It has the familiar Wiha handle that used on their screwdrivers, along with a collet use to hold razor blades.

Catalog Entry

Taking a look at the catalog entry we can see that there are multiple options for buying the scraper with and without blades as well as a selection of blade kits.   There are five different blade styles that can be bought in quantities of 10.  There is also replacement blade set that contains two of each blade.  While most people will buy the 43090 kit that includes the scraper and 10 straight blades, the scraper can be purchased separately under part number 43040.

Catalog Entry

All of the blades are made in USA, while the actual scraper is made in Germany.

Scraper Handle

Now looking at the scraper, the best feature about it is the familiar Wiha handle.  The scraper handle looks to be the same size as Wiha’s largest handle style, which is used on the larger Philips and Slotted screwdriver blades.

43090 Kit with Blades

I bought the 43090 kit that includes 10 straight edged blades.   The blades come in this small plastic container that reminds me of old film canisters.

10 Blades Included with the Set

I’m not sure who the actual OEM manufacturer of the blades are since there are no other markings on the blades themselves.

Reverse side of blade

Taking some measurements of this particular blade style, it comes in at ½” at its widest point, and 11/32” at the narrow part that is inserted into the scraper.  They are also about 1.75 inches or 45mm in length.  The hole in the blade serves no real purpose in this application.

While we have the calipers out, we’ll take a measurement on the diameter of the collet and it comes out to 15mm.  The length is just under 33mm from the top of the handle.

Blade-Holding Collet

Unscrewing the collet, we can see that there is some sort of anti-seize compound applied to the threads.

Internal Threads of collet

I guessing that this is to prevent galling up the threads.  It looks to be a copper-based anti-seize, which would be the appropriate base to use for aluminum applications.  I’m almost positively that the collet is made out of aluminum.  It is non-magnetic and is much too light to be stainless steel or brass.  The blades on the other hand are magnetic as expected.

A closer look at the threads on the collet, there was definitely a very liberal application of anti-seize compound.  I kind of wonder if this is a manual step in the production process.

Inserting a Blade

To insert a blade into the collet, just loosen it up enough to slide the narrow end in and then screw it down to clamp the blade in place.

Blade holding collet

I want to point out a very distinct feature that Wiha could have easily overlooked.  On all Wiha screwdrivers there is a flat spot that they advertise as an anti-roll feature.  When you are holding a Wiha screwdriver this flat spot is the most natural spot to place your thumb.  The scraper is manufactured in a way that the tines on the collect align with this flat spot so that you can use the blade at both a zero and 90 degree angles.  The reason I mention this is because this tool would not be nearly as useful without this alignment.

Suggestion – Blade Storage in Handle

If I had one suggestion, it would be to have a place to store the blade within the handle so that you don’t need to separately carry around this canister of blades.  It seems like there would be plenty of room in the handle to have a cap that screws off to reveal a couple of spots for blades.  We all know that that small plastic container is going to someday pop open in your tool bag and you don’t want to be digging around with those razors loose.

Suggestion for Storage of Blades in Handle


To test this thing, I’m first going to try and remove these inspection date labels on this Fein tool.   These are stickers that are designed to be tamper resistant so they are not very easy to remove in one piece.   The tool performed quite well for this task.  The difference between this tool and your standard scraper is the much greater level of control you get with this larger handle.

I also used this scraper to remove some tape that probably has been affixed for 50 years from a metal tanker desk I’m restoring.  I was totally expecting it to mess up the paint, but to my surprise I was able to scrap that tape off without damage to the underlying surface.

For under $20, this is a great little set that comes in handy if you are doing a lot of restoration jobs that require scraping off old glue, labels and tape.
