Thank you, critterologist.
I did buy this leaf rake a while back. I love it for cleaning out between my shrubs. It would not work as well for dethatching, but it is a pretty well made little rake for a decent price. Feels very balanced in the hands and has a long reach. Recommend this one to anyone looking for this type of shrub rake. It reaches into a lot of tight spots for me aside from behind the HVAC unit which requires either a broom or a leaf blower. In any case, I am very glad I invested in this little rake.
