the large number of crimped, twisted, curled, and clumped hinges
Opinion
This is actually a good thing ! It is just a blink away from being a benefit. Like a good guitar player, you need practice.
1, This only applies to those whom are experienced with "Long Nosed Pointy Tongs"
Using any other tong, no need to bother reading on.
1, With the long pointies, grab a clumped bundle, gently prise the clump open, with gum facing down.
2. hold the opened clump (like a pair of pliers) with the pointies.
then bend the hinges length ways around one leg of the tongs.
That's it !
They will lie on the table flat. with a crease lengthwise.
Dab you moist finger on the top hinge and it will lift off the clump. (un gummed side)
You have 10 or so hinges ready to apply.
Sounds terribly involved, but actually you can do in nano seconds with practice.
Part of good Philately is having the right tools, and the experience to use them, as in any discipline.
PS: you cannot blame the hinge maker, gum has it's own peculiarities driven by Gum Arabic and Humidity.
