Fast Fixes ... At Home
Problem Grime and stink
Solution "Never put your pack in a washing machine or dryer," says George McCloskey, technical specialist for Gregory. After long trips and before each season, clean it inside and out with a dry brush to loosen dirt and debris. Vacuum out the remains, then wipe it with water and a non-detergent soap such as Woolite. Never use hot water, bleach, dishwashing liquid, presoaking solutions, or spot removers. To dry, stuff the pack with newspaper and hang in the shade.

Problem Water-repellent treatment no longer beads
Solution Recoat the pack with Nikwax Tent & Gear Proof ($12,

Problem Snagging zippers
Solution Vacuum dirt out of zipper crevices, then scrub with a toothbrush and cold water (this is good prevention, too), especially after camping in dusty or sandy areas. Phil Mesdag, product manager for Sierra Designs, recommends lubricating the zipper chain with McNett's Zip Care ($5,; lip balm or paraffin wax will do in a pinch. (Note: This technique works for all zippers—tents, bags, and apparel included.)

Problem Frayed fabric
Solution Critters love to chew on salt-soaked shoulder straps and foam backpanels. Pinch the torn edges and use Super Glue to create an instant "stitch" (smear it along the rip). Then apply Seam Grip to make the repair more permanent.

Problem Hole or tear in packbag
Solution Patch it with Coghlan's Nylon Tent Repair Kit ($5, "Make sure the fabric is clean and dry before applying," says McCloskey. Trim the hole's edges (this improves adhesion), then stick the patch on the inside of the pack. Press firmly from the center out.

Fast Fixes ... In the Field
Problem Broken buckle
Solution If you break an essential buckle (like a hipbelt or shoulder strap), find another (try a compression strap or the lid) and cut it it off. Locate the thin plastic bar that the webbing loops over on the broken buckle. Cut a small slit in the center of the same bar on the replacement (use a lighter or stove to heat your blade if the plastic is hard to slice). Thread the strap through the slit on the buckle and secure with duct tape. Tip: Stock a Quick Attach buckle ($4 for an assortment,, which comes with a precut slit.

Problem Zipper blowout
Solution If the coil is split open, gently squeeze the slider with pliers and move it up and down to realign the coil. No pliers? Close the gap with safety pins and get it repaired.

Unless you heat the knife to red hot, you will not change the temper. The reason you are not supposed to put knifes in the dishwasher is for the sake of the handles, and the safety issue of having sharp objects laying around in the washer drawer.

Oct 25, 2009

A lighter will def change the tempering of the blade.

Jul 08, 2009

You'd be surprised how little heat it takes to ruin the temper of your knife's blade. You shouldn't even wash good cutlery in a dishwasher because over time you'll ruin it's ability to hold an edge.

May 12, 2009

Heating a steel knife blade enough to melt the plastic will not harm it at all. A small lighter or match cannot heat the steel enough to affect the heat treatment. If you take a welding torch or something that would be a different story.

Apr 30, 2009

If you cut through the buckle I would want to melt it so it forms back together to further strengthen before taping. I would do this assuming a replacement would be used when back from the trip.

Apr 22, 2009

Heating your knife blade will damage it permanently, use it as last resource.
