You can also polish and shape the pin heads and collars by applying a good metal polish on a folded terrycloth, heavy cotton towel, or leather, then briskly rub the razor on the towel or leather, with the pinned collared razor.

It is easier to pre- polish collars prior to pinning. You can make a mandrel with a small screw or bolt and nut, then chuck in a hand drill, drill press or Dremel and buff on polish charged cloth or leather.

Foam nail files also work well for shaping pins, many are diamond impregnated and are inexpensive.

Next time try to match the taper angle to the tang angle, make the wedge thinner, and the scales also when using a backer.

Try doming the collars. You can make a doming dapping block with a ball bearing and piece of hard wood, to dome your collars.

They will look more finished and will keep the pins under tension. Watch how the scales flex while opening and closing, it is not any wonder why pins loosen over time. It is also probably why most vintage razor makers used domed collars of one sort, even slightly domed collars offer some flexing and compression.

Sand the inside of the scales over a cookie sheet, to save the dust, then fill the cracks with the fine dust and dab on a few drops of CA glue. Sand flush for an invisible crack repair. It may take more than one application. CA kicker will speed up the repair. Look at some of Outback’s seamless crack repairs.

Nice save, be careful, it is addicting...
