DAMMERRs are carefully crafted, scientifically designed rock climbing hammers. Each DAMMERR is hand made and is to some degree unique.

Please note that DAMMERR is correctly spelled with two R's and in caps. DAMMERR is a mashup of my name and the word hammer.




A Little About Me

I am a climber and prefer back country trad routes where I can climb at my level without the heckling of other climbers. I occasionally make first ascents of routes placing bolts where necessary but I have never used a power drill.

I am an engineer and taught engineering at a university for 30 years. I have retired from teaching but continue to work as a forensic engineer.
