Clippers:

For basic hand clippers(secateurs) and loppers, I'm happy with Corona brand because they're strong, simple, and reliable, and I get them at Walter Andersen Nursery: 

http://www.coronaclipper.com    I particularly recommend the forged 3/4" basic hand secateur, and the 26" Orchard Lopper.

Hand Saws:

For hand saws that I use for pruning, I use both Corona(above) and Silky Saws.

http://www.silkystore.com     http://www.silkysaws.com     

My two favorite models are the Sugoi 360, and the Ibuki 390, both suitable for cutting up to around eight to ten inch diameters.  Silky has a vast array of saw models and sizes to choose from for a variety of uses including pole saws with up to 21' extension, root pruning saws, and various artisanal carpentry saws.  They have dozens of saw models to choose from for the variety of uses.

On a related note, Sawz-Alls, which are electric, with a cord usually, and with blades being sharp, are easier maintenance than chainsaws, though about 3 to 4 times slower cutting, yet make quick work of shrub and small tree demolition, up to about one-foot trunk and limb diameters, plus you can more safely cut roots with dirt interacting with the blade, - in some cases more safely and less problematic than with a chainsaw.

Hauling and Recycling:

Andres Demolition and Hauling, skidsteer/bobcat services:  619 298 3636     -   Fully equipped and efficient, have him scrape out your lawn, vegetation, and all other construction materials and concrete, to haul away in his huge heavy duty trailer.
