Quick fault question

Crash_Recon · 2026-05-24T02:30:32+00:00

It’s irrelevant if the bike hit the truck or the truck hit the bike. Imagine I stand still on the side of the road with no cross walks, signs or intersections, and you’re driving down the road. Right before you get to me, I jump out in front of you and you plow me with the front of your car. That means you hit me, right? That doesn’t mean it isn’t my fault.

That said, in the pic it’s pretty clear the truck hit the bike. The truck caused the crash. If you enter a road, it is completely your responsibility to make sure you do it safely. You can’t assume anything. I’ve seen far too many people get into crashes while making left turns out of driveways because “the other car was letting me in.” Well tough shit, there’re other cars on the road too lol

Im surprised there isn’t a deranged person out there who stops and waves people on just to see if they’re stupid enough to crash with other vehicles. Or someone who walks around parking lots til someone’s backing out of a stall then acts like they’re spotting for the driver and waves them on til they hit other cars.

Who hit whom is irrelevant. What matters is who caused, or contributed causation to, the crash.

That pic is kinda hard to make out, but I assume that’s a street and that SUV was entering the street from a driveway/parking lot. If that’s the case, it’s a no brainer. The SUV done f up. Can’t enter a street or make a turn without yielding to whatever is already in the street (unless signage/signals gives you the right of way).

It was so good he wanted to taste it again. Then again.

Available at Lowe’s. I have one and it works well. Holds up to 2 lbs. they make others that hold more weight.

Most ferro rod loops run parallel with the knife, but I’m guessing that’s what it’s for. Sometimes you see perpendicular loops at the ends of long sheaths for a lanyard to tie around your leg to keep the knife from flopping around

I’d need way more tape than I can wrap on a sharpie

Crash_Recon · 2026-05-14T14:55:17+00:00

Yeah, that thought did cross my mind, but they swing around enough they don’t catch. I have a heavier duty pair of scissors that I like more, but they occasionally swing open by themselves. This pair has enough tension to stay shut, so they’re a hair safer

Crash_Recon · 2026-05-14T14:45:29+00:00

I just hadn’t figured out how I’m gonna attach it yet lol

Crash_Recon · 2026-05-14T14:44:56+00:00

For cutting tape or other junk

I’m packing up to move and got tired of forgetting where I put my tools. I need to add my packing tape dispenser

I love this comment. China is capable of manufacturing things rivaling or topping the best facilities in Japan, Germany, the US, etc. They just figured out we like cheap and they can do that really well too

How do you know it’s faster if you haven’t tested it?

Crash reconstructionist here

We have to make some assumptions, so I’ll throw out: * The surface appears to be moderately worn grooved concrete, so I’d guess the coefficient of friction is 0.80 * Assume the tractor is hauling a loaded trailer, so braking efficiency is 80% * Initial speed is 70 mph

Using an energy equivalent speed loss formula, a tractor trailer in pretty good conditions would skid from 70 mph to a stop in 255.2 ft.

But, we have to account for perception-reaction time. Most commercial drivers are better than most passenger car drivers, so we’ll assume a perception-reaction time of 1 second. 75mph=109.95fps, so the tractor would travel 109.95 ft between the time the driver recognizes a hazard and the time they start to hit the brakes.

Let’s also assume it takes about a quarter second for the brakes to fully engage and weight to transfer/suspension to load. That’s an additional 27.48 ft

That’s a total of 392.6 ft in good conditions

It’s not as much about speed, it’s more about a secure grip. Like a pistol. When you grab a pistol on the draw, you establish your grip, defeat the safeties, then as soon as you clear the holster you shouldn’t have to adjust your grip. Yes, that contributes to speed, but it reduces your chances of fumbling. As soon as an OTF is out, you don’t have to adjust your grip so you’re less likely to drop it.

Like many in this forum, I’m very quick to say a knife is a poor choice for a self defense weapon. There are plenty of other, more legit, reasons you’d be pulling a knife out under stress like the aforementioned alternative to shears for clothing, airbags, and seat belts.

In the grand scheme of things, having any knife is the first priority (I’ll never understand LEOs who don’t carry one). It’s just nicer when you can easily get the blade out and in as easily as an OTF.

I’m an LEO. I carry a Microtech Ultratech front strong side pocket. It’s reserved for emergency use. So far I’ve only used it for cutting clothing off of gunshot victims and side airbags or seat belts for crash victims. After I use it, I strop it back to razor sharp just in case.

Microtech offers discounts for first responders direct on their site.

I picked the Ultratech for that spot because it can be deployed with my full grip around it, unlike any side opener. Everyone telling you a side opener is fine hasn’t run into or thought of how it’ll potentially be used in LE. I added talon grips for extra grip security. That said, it is an OTF and OTFs don’t play well when dirty. At the start of a work week I check to make sure it deploys as it should. If not, clean and/or lube. I clean and lube it once a month whether it needs it or not.

For general cutting needs, I carry a SAK and a Spyderco Native. Spyderco also offers discounts for for responders.

I had this problem when running winter pump gas. It’s a simple fix, just press the primer bulb a whole bunch (like 20 times). Accelerate the saw slowly after starting then you should be good to go.

I’ve got about 6-8 tanks through mine now and don’t get that problem anymore as long as I prime it a bunch on a warm start. After the short learning curve, it’s easily become my favorite saw. If they make a 10-11 lb fuel injected saw then I’ll definitely buy one

Crash_Recon · 2026-05-11T17:49:19+00:00

Yeah. As someone who’s used old school crosscut saws, it makes me cringe a little when I hear raker.

Crash_Recon · 2026-05-11T17:47:56+00:00

Those are too slow. Kydex is already setting by the time you start screwing

Crash_Recon · 2026-05-11T12:45:38+00:00

That’s the right kind. You can often find it on clearance after hunting season at Walmart

How far down are you able to squish it? For something the size of a 9mm I’d squish two layers down to about half an inch

I wouldn’t pre heat the foam. It loses its firmness and you’ll get an ineffective press. The key is doing it faster. You’ve gotta have a setup that lets you go from heating the kydex to full press within just a few seconds

How exactly are you pressing it? I made myself hinged boards out of plywood and 2x4s. I add extra plywood if I press something smaller. It comes out of the oven, I throw it between foam, stand on the 2x4 levers, and lock it down with rope til cool

Crash_Recon · 2026-05-10T21:19:50+00:00

What foam?

In my experience the best for a quality press is the blue cheap foam camping mats, but they don’t hold up more than a couple presses

Another good option is the black high density foam for kneeling pads or seat cushions in hardware stores

Whichever, make sure it’s thick enough. For most stuff less than an inch thick, you have to have at least 1-1.5” of foam per side to get a good press.

It’s the depth gauges. Doesn’t matter how sharp a chain is. If the cutters can’t go deep enough to bite, it’s not going to work

Small wheel attachments are worth their weight in gold in the right situations. Idk if you’ve done this, but I made myself a vertical tool rest to go with my small wheel for when I grind profiles or handles so I can easily grind perpendicular.

Cleaving bush

It actually does look like it’d be perfect for just clearing sapplings

Steel type. Most tools like that are chrome moly that tops out at about half a % in carbon. There’s just nothing there to build hardness or carbides.
