spyderco compression lock patent

Stop Pin Blade Anvil Cutting instruments have been used for centuries by craftsmen, hunters, and others requiring a sharp cutting instrument. During failure, the liner lock has a tendency to bow or otherwise deform, due to the extended length of the liner lock and the thin nature of the material required to fit within the knife handle cavity. However, more typically various laminated or ornamental types of handle scales would be utilized by gluing and/or attaching the handle portion to the blade locking mechanism 22. A stop pin 12 is typically interconnected to the handle 14 near the upper edge and extends within the cavity 58. Alternatively, the stop pin could be an extension of the locking mechanism prevent overtravel by the knife blade 4. It's possible to disengage the compression lock accidentally when twisting the knife during a cut or squeezing very hard while cutting due to the exposed nature of the lockbar - almost the same issue as with liner locks, just on the back of the handle and not the front. Handle Upper Edge More specifically, a lock push button 44 is provided which engages the lateral surface of the locking mechanism 22. 14 If I'm actually gripping the knife for use though, I find the back lock less awkward to close and the bias towards being closed is a nice bonus in pocket. 17, yet another alternative embodiment of the present locking mechanism is shown. Rear Scale The stop pin 12 is typically provided to prevent the knife blade 4 from overtraveling when the blade is in a first extended position of use and force is applied to the cutting edge 6 of the blade 4. 4; FIG. 1 with the stop pin removed for clarity in the upper drawing; FIG. I think I prefer the compression lock but mostly because it allows for better "packaging". Is this because in your experience or opinion the back lock is more reliable and safer or is it because the compression lock gets in the way of a specific method of opening and closing said knife? Referring now to FIGS. 10 Assignors: FORD, VINCE, GLESSER, LOUIS S., JHONES, PETER H. HAND-HELD CUTTING TOOLS NOT OTHERWISE PROVIDED FOR, Hand knives with adjustable blade; Pocket knives, Hand knives with adjustable blade; Pocket knives with pivoted blade, Hand knives with adjustable blade; Pocket knives with pivoted blade lockable in adjusted position, Hand knives with adjustable blade; Pocket knives with pivoted blade lockable in adjusted position by a spring tongue snapping behind or into the tang of the blade from a side part of the handle, Surefire, Llc, A California Limited Liability Company. Thus as depicted by the arrow in this particular embodiment which identifies the respective direction of movement, when thumb pressure is applied to any part of the upper portion of the rotating lock mechanism 48 in a direction substantially normal to the longitudinal length of the handle, the tang 24 will become disengaged from the blade anvil 20. I think it's one of spyderco's best designs. More specifically, a rotating lock mechanism 48 is provided which allows the tang to swivel in and out between the blade anvil 20 and the stop pin 12. I had a thought the other day, when I was thinking about trying a left handed pm2, it kind of occured to me. Blade Aperture 18 Especially for larger blades which is why they designed a self close mechanism for the szabo folder. Mostly on my G10 para 3. Alternatively, a ball detente type of mechanism could be used for the same purpose. Sliding Button Release Thus, when a force is provided downward on the blade upper edge 8, the tang 24 of the locking mechanism is compressed between the stop pin 12 and the blade anvil 20. liner lock, it works beautifully on the Military and I think it would be a shame to change that, I guess I shouldn't speak for everyone, but at least for me I just simply. Several past, present, and future Spyderco knives utilize the Compression Lock (such as the upcoming Sage 5 Lightweight). Thus, it is intended that the appended claims be construed to include alternative embodiments to the extent permitted by the prior art. Lock Swivel Release Spyderco has done other knives in the same model with back locks, liner locks, and compression locks. 1. 32 Postby Doc Dan » Tue Jan 28, 2020 10:07 am, Postby Mushroom » Tue Jan 28, 2020 10:15 am, Postby Pancake » Tue Jan 28, 2020 10:30 am, Postby Wartstein » Tue Jan 28, 2020 10:31 am, Postby James Y » Tue Jan 28, 2020 11:04 am, Postby Wartstein » Tue Jan 28, 2020 12:03 pm, Postby Mushroom » Tue Jan 28, 2020 12:09 pm, Postby Evil D » Tue Jan 28, 2020 12:25 pm, Postby Wartstein » Tue Jan 28, 2020 12:29 pm, Postby Evil D » Tue Jan 28, 2020 12:29 pm, Postby Doc Dan » Tue Jan 28, 2020 12:33 pm, Postby Wartstein » Tue Jan 28, 2020 12:37 pm, Postby VashHash » Tue Jan 28, 2020 12:37 pm, Postby Evil D » Tue Jan 28, 2020 12:42 pm, Postby Evil D » Tue Jan 28, 2020 12:46 pm, Postby PStone » Tue Jan 28, 2020 12:52 pm, Postby Evil D » Tue Jan 28, 2020 12:56 pm, Postby Wartstein » Tue Jan 28, 2020 1:01 pm, Postby Mushroom » Tue Jan 28, 2020 1:10 pm, Users browsing this forum: Ankerson, bear71, bobnikon, Larrin, Lumpy620, Mr.B., RAHCommanche, Rp5 and 53 guests.
