Corona Clipper Company Pruning Tools
Corona Clipper Company is a long-established California manufacturer of professional horticulture cutting tools including bypass pruners, anvil pruners, loppers, and harvest shears. Corona tools are used in commercial nursery, greenhouse, and landscape operations where cutting quality, ergonomics, and durability across high-volume use are the primary requirements. Their product line spans hand pruners in several blade configurations through long-reach loppers sized for woody plant management in commercial growing environments.
Bypass vs. Anvil Pruners
Bypass pruners use two curved blades that pass each other like scissors, making a clean cut that minimizes tissue damage - the preferred tool for pruning live stems and green growth. Anvil pruners use a single straight blade that closes against a flat anvil surface, producing a crushing cut better suited to dry or dead wood. For indoor growing, canopy management, and harvest applications involving live plant tissue, bypass pruners produce cleaner cuts with less stem bruising. Corona's bypass pruner line includes options from lightweight mini pruners for fine canopy work through full-size models for mature woody stems.
Maintenance and Longevity
Corona pruners are designed for long service life with proper maintenance. Keep blades clean and free of plant resin with regular wipe-down using isopropyl alcohol. Sharpen bypass blades using a whetstone or pruner sharpening tool when cutting performance decreases. Apply a small amount of lightweight oil to the pivot point seasonally. Replacement springs and blade sets are available for most Corona models, extending service life significantly beyond lower-cost alternatives.

Corona Clipper FAQ
What is the difference between Corona bypass pruners and anvil pruners?
Bypass pruners use two curved blades that cross each other like scissors to make a clean, precise cut on live green stems - minimizing cell damage and leaving a clean wound that heals quickly. Anvil pruners use a single sharpened blade that closes against a flat surface, crushing the stem in half. Anvil pruners are better for dry or dead wood where the crushing action is acceptable, and they are easier to sharpen. For indoor growing, canopy training, and harvesting live plant material, bypass pruners are the correct choice - the clean cut they produce reduces disease entry points and minimizes stress to the plant.
How do I sharpen Corona bypass pruners?
Sharpen only the beveled outer face of the curved cutting blade - not the flat inner face. Use a diamond whetstone or a dedicated pruner sharpening tool, drawing the stone along the bevel at the original factory angle (approximately 25-30 degrees). A few passes is typically sufficient to restore a sharp edge. Do not sharpen the flat inner blade; this side should remain flat. After sharpening, clean the blade with isopropyl alcohol, oil the pivot, and test on a green stem - a sharp bypass pruner should cut with minimal force and leave a clean, flat cut surface.
How do Corona pruning tools compare to Chikamasa scissors for indoor growing?
The two tools serve different tasks. Chikamasa precision scissors are optimized for fine trim work - small stems, leaf cutting, and detail work where blade precision and reduced hand fatigue during extended sessions are the priority. Corona bypass pruners are better suited to canopy training, cutting larger stems (1/4 inch to 3/4 inch diameter), and harvest cutting of larger stalks and branches. Most professional growers use both: Chikamasa or similar fine scissors for trim and detail work, and a quality bypass pruner for larger canopy management and harvest cuts. Both types are available at Hydrobuilder.
