Thread: ivory handle

i have 7 day set ivory handle razor 's. Problem is most handle has crack in it. i will post pic it later

I've got a solution for cracked ivory that nobody has ever thought about...dental composites (used for those tooth colored restorations).

PA Dental - Composites

All you need to do is do the sanding you want to do, then use a dremel to carefully enlarge that crack a bit. After that, use an etchant for 30-60 seconds and wash it off. Apply for dental composite and cure it using a UV light (or put the scale outside for an hour or so). Dental composites should be ideal since they're compatible with your ivory (heck they're compatible with your own teeth) and provide great strength. On top of that, you can order them in different colors based on the color of your ivory. If you want to know exactly what color you need, take the scales into your dentist and kindly ask if they can use their shade guide so you have a reference point for your purchasing. Might also ask the dentist if you can buy the dental materials directly from him if you want to avoid using the internet.

That is brilliant! I don't know if I'll ever use this knowledge, but I'm glad I learned it.

An additional note that dental composites come in three varieties: macrofilled, microfilled, and hybrid.

Microfilled composites have the smallest fill particles and produce the best shine when buffed but at the expense of some strength...these are generally used for anterior teeth.

Macrofilled composites have the largest fill particles and do not shine up like their microfilled cousins but produce the strongest restorations...these are generally used for posterior teeth.

Hybrid filled composites have both large and small fill particles and provide the best of both worlds as they generally shine up well while providing the strength of macrofilled composites. These days, most dentists use hybrid composites for most restorations.

I also forgot the bonding agent...you'll need a bonding agent to get the composite to lock super tight to the ivory...so in recap, here's your steps:

1. clean ivory scales as best as you can...use water to get as much crud off as you can.
2. use a dremel to slightly open up the cracks.
3. use etchant to open the microscopic pores of the ivory.
4. wash off etchant for recommended time using water. then dry completely
5. apply bonding agent and allow to dry
6. apply dental composite to cracked area and allow to dry in the sun if you don't have a UV light.
7. sand to finish.

The colors for dental composites come as A1, A2, A3, B1, B2...you get the idea. When your dentist gives you the shade, it will be in this format and will aid you in purchasing your materials. The etchant and bonding agent are colorless and shouldn't be a problem.

Well, this is how we do it in the office. There's a couple more steps, but I've left them out since you don't have to worry about recurrent decay, microleakage, etc. when you're repairing ivory scales.

Razor name is TORNHILL 44 NEW BONDS

Absolute brilliance, its so simple its stupid! Meaning I should have thought of it.

@ Sham, lots of Ivory scales have a crack at the pins, usually the pivot. It does reduce the value , but not by much. I would not worry about it unless it creates a problem with function.

I was thinking your razor might be Truefitt and Hill, but that didnt track (there never was a truefitt and hill on new bond street, just a truefitt). Anyway, someone got a set like yours a while back. Its "Thornhill 144 New Bond st"

Excellent thinking!

Amazing some of the logical solutions to things that folks come up with here! Seems that sometimes a problem has a solution sitting right under our noses and we simply overlook it - literally!

Looks like that's going to be one sweet set when you're done with them Sham.
