Literally thousands of manyears have been spent by craftsmen to figure out how to make better razors; Craftsmen in many different places of the world, who did nothing but make razors and scales for their entire career. They all ended up with very similar designs. For someone to say that they know better after making a razor or 2, is arrogance, plain and simple. If you don't see why they didn't do, X, you probably need to look harder instead of assume they all missed something blindingly obvious.

If spacers were just as good as wedges, they would have used spacers, since they're easier to make and easier to use.

too many knifemakers think that a razor is just a funny shaped knife, and refuse to learn.

A friend of mine is fond of saying "Before you start thinking outside the box, you should look at what is inside the box and why".

Thanks for the informative read.

I learned a thing or two and shall never look at the spacer wedge in the same light.

Thanks, I'm now a wedge/tang expert .(in my own mind)

I have a T.I Razor here with a tapered tang and a spacer.. Would that be why the blade loosened off?

If the scales have no flex and that is why a spacer was used, as the blade moves through it's range of motion the scales are not moving with the taper in the tang creating tight and loose spots. If the tang has a taper, and a spacer is used when it gets to the fast part of the tang at the point where it should flex it pushes the pin. Repeat the process and the pin is always loose.

The scales do have flex. I think its poor workmanship.

It should be noted that if the scales have no flex, then even with a spacer, modified pivot point washers will need to be utilized. Otherwise, because of the tang taper, when opening and closing the razor, pressure will be put on the scales to bend. This will create stress points leading to loose pins and possibly broken scales. Unless there is no tang taper. But most blades have tapered tangs.
