A blade flipper is a knob at the back of a knife that you flick down and it opens the knife example kershaw skyline line usally opposite from the blade
A drop point blade has a convex curve of the back, the opposite side of the cutting edge, towards the point.
any saw is the opposite of the way the blade spins!
The sharp side is opposite where you would normally expect it, while the normal cutting side, is the wide unsharpened portion of the blade.
The opposite direction that the blade rotates. In this case I would say counter clockwise but their should be a marking somewhere on the mower that shows blade rotation direction.
Literally translated, light blade would be 'hikari no katana,' written: 光の刀 I would suggest that instead of "dark blade," you go with "shadow blade/blade of shadows," as not only does it sound better than the literal translation of "dark blade," but also stands better as an opposite to a "blade of light." That would be 'kage no katana,' written: 影の刀
You begin by removing the blade from the plate joiner while wearing gloves. Soak the blade with a cleaner spray and allow it to sit for a few minutes. Afterwards, use a cloth to wipe the blade in a circular motion. Repeat for the opposite side. Perform a final inspection to ensure that the blade is completely clean and free of debris. If the blade is still dull and dirty, it may need to be replaced.
They usually have a pin or locking knob, you either push it in or hold it in while you loosen the blade retaining nut, some you might have to remove the shield or guard, older saws might not have this feature at all, place a piece of wood on the bed of the saw and hold down so the blade digs into the wood and loosen the nut.
Depends on the manufacturer and if the saw is left or right handed. Normally a saw cuts UP rotating in the opposite direction a wheel would. Click the saw on, without a blade in to see which way the motor turns then put the blade in to cut in that direction.
The tail rotor is moving "perpendicular" to the main rotor, not "opposite". The tail rotor creates thrust opposite to the thrust of the main rotor, to keep the fuselage from spinning. Most helicopters spin the main rotor counter-clockwise looking from above, which puts a clockwise rotation on the fuselage. You need a tail rotor pushing the tail counter-clockwise to keep the fuselage pointed in the direction the pilot chooses.
