WW1 razors

I'm curious to know whether the razors were poor quality or whether the just weren't sharp. Found a WW1 army online razor online and it looked pretty decent from the photos. That might have been one issued to officers I guess. I wonder how many soldiers owned a razor before joining up if the army had to issue them. Keeping them dry and maintaining them must have been a major challenge.
Officers would have had their own razors and probably a porter to sharpen it for them. The average Tommy couldn't afford a decent straight so had to use the military issues. 4 days in the front line they wouldn't need to shave or be particularly fussy about uniform but once away from the front line they had to smarten up. Full kit, buttons polished and clean shaven.
Until the gas shells started dropping, from my time in the army they used to tell us that anymore than 3 days stubble and you wouldn't get an air tight seal on your respirator, and that's with modern rubber and the benefit of years of research, the gas masks those poor sods had would probably struggle to seal over a days growth.
