I wasn't a fan of the plastic handle and also thought the blade was too flimsy.

I have used this several times now for spackle, and I wash it with hot water. I dry it thoroughly with a towel and it still looks like the day I bought it minus some scratches/wear and tear.

The second day, this stuff already get rust...

I purchased this putty knife from the wall paper removing set. It does a good job for what it is intended to do, but be ware that the back edge of the putty knife is very sharp. Using it to remove wall paper means using it with wet, slippery hands...and even being careful, my hand slipped and I cut my hand in three different places. Fortunately, a couple of bandaids is all I needed, but it could easily result in a trip to the emergency room for stitches. Just be careful. Also, the saying that y...
