I'm still processing this - and hope to update the story when I have more time and info.
But the basics.

I've been shaving with a Straight for over a year now and enjoy it more than I ever imagined.

My Grandfather was a Barber from Sicily, arriving in the US shortly after WWI.
When my Dad was a teenager one of his chores was to hone (touch up) Grandpa's razors at the kitchen table. When I shared my interest in shaving with a Straight with my Dad (82) and showed him my collection he related the honing story, one I had never heard.

Saturday these two arrived in the mail:

Name: Grandpa Razors Low Res.jpg Views: 617 Size: 29.1 KB

The front razor is an HMC The Bossing Razor - Front tail has a Hammer, back tang is marked "Hand Made in the USA Providence RI with an anvil. You should be able to make out the HMC Heart Logo and Providence RI and arrow on the scales. <6/8 (11/16) at the middle of the blade, slightly toe worn.

The back razor is marked HM CHRISTENSEN CO BROCKTON MASS (front) and WARRANTED on the back. Measures 11/16, very little and even hone wear. The scales appear to be celluloid. The pivot pin is loose and it has to be guided to the scales.

Gave them a very light, gentle cleaning for the picture.

From the little I have had a chance to read on the Wiki HM Christensen was in business from the 1860's to the 1905 when the company was sold, changing the name to HMC in 1916.
Any dating help and corrections would be appreciated.

My Grandfather gave the pair along with a ACE Allover Mfg. hair clipper (not shown, came in the package) to my Dad around 1952 shortly after he and Mom married. I have no memory of Dad using the razors but he used the clippers to trim our crew cuts when I was a tot. (to this day we use the term "cleana uppa you neck" (insert Italian accent) to refer to any in between the barbershop hair trimming)

When we talked about this today during our Fathers Day call, and I was able to give him some of the history, I have to admit I was overwhelmed. Dad related that Grandpa would take the clippers and the rest of his Barbers Kit to the Rest Home on Sunday afternoons to give those who could not get out a shave and a haircut.

A Father's Day gift that spans three generations...
