David S Day 4

 4/6 and no chance at more.

1. Strain :), D32. Far from a gimme, this took up most of my time. I was debating between a few answers, but strain is all that seemed to work. 
2. Stiletto :), D10. Seemed like the clear guess. Was a little worried I’d be wrong and waste my low Ds. 
3. Bloody Mary :), D01. Only thing I could think of that remotely fit. 
4. Blizzard :(, D21. No idea and have never heard of Valve. 
5. Horse :), D22. Have heard of this many times and seen the photo. Not sure how widely known this is. 
6. All the Light We Cannot See :(, D13. No idea.
