I've enjoyed compiling this corkscrew guide, I hope it can be of assistance to you. If you'd like to get in touch it would be great to hear from you. Peter@corkscrewsonline.com
A vast variety of corkscrews can be found with tusk, antler & horn as handles. The most simple of designs in stag you'll probably find for around £5.00. Searching hard will yield some interesting variants including at the top end some fitted with very ornate silver caps.
I love these - a wonderful group of old Stag & Horn corkscrews.
